ZANESVILLE, Ohio — Tim Ryan is a “crazy, lying fraud.” That’s how J.D. Vance, the best-selling memoirist turned Republican Senate candidate from Ohio, opened his remarks at his September rally alongside Donald Trump in the middle of the congressional district Mr. Ryan has represented for two decades.Mr. Ryan seems like an unlikely object of such caustic rhetoric. A 49-year-old former college-football quarterback, he is the paragon of affability, a genial Everyman whose introductory campaign video is so innocuous that it might easily be mistaken for an insurance commercial. His great passion, outside of politics, is yoga and mindfulness practice.“We have to love each other, we have to care about each other, we have to see the best in each other, we have to forgive each other,” he declared when he won the Democratic Senate primary in May.He isn’t just preaching kindness and forgiveness. For years, he has warned his fellow Democrats that their embrace of free trade and globalization would cost them districts like the one he represents in the Mahoning River Valley — and lobbied them to prioritize domestic manufacturing, which, he argued, could repair some of the damage.His efforts went nowhere. Mr. Ryan failed in his bid to replace Nancy Pelosi as House minority leader in 2016. His presidential run in 2020 ended with barely a trace. And his opponent, Mr. Vance, was expected to coast to victory this year in a state that Mr. Trump carried twice by eight points.But things haven’t gone as predicted. Mr. Ryan is running close enough in the polls that a political action committee aligned with Mitch McConnell, the Republican Senate leader, has had to commit $28 million to keep the seat (now held by Rob Portman, who is retiring), and Mr. Vance has had to ratchet up his rhetorical attacks against this “weak, fake congressman.”After years of being overlooked, Tim Ryan is pointing his party toward a path to recovery in the Midwest. On the campaign trail, he has embraced a unifying tone that stands out from the crassness and divisiveness that Mr. Trump and his imitators have wrought. A significant number of what he calls the “exhausted majority” of voters have responded gratefully.And his core message — a demand for more aggressive government intervention to arrest regional decline — is not only resonating with voters but, crucially, breaking through with the Democratic leaders who presided over that decline for years. The Democrats have passed a burst of legislation that will pave the way for two new Intel chip plants in the Columbus exurbs, spur investment in new electric vehicle ventures in Mr. Ryan’s district, and benefit solar-panel factories around Toledo, giving him, at long last, concrete examples to cite of his party rebuilding the manufacturing base in which the region took such pride.In short, the party is doing much more of what Mr. Ryan has long said would save its political fortunes in the Midwest. The problem for him — and also for them — is that it may have come too late.Mr. Ryan is a genial Everyman who says, “We have to see the best in each other, we have to forgive each other.”Gaelen Morse for The New York TimesTim Ryan was not always so alone in Congress. Manufacturing regions of the Northeast and Midwest used to produce many other Democrats like him, often with white-ethnic Catholic, working-class backgrounds and strong ties to organized labor. (Mr. Ryan’s family is Irish and Italian, and both his grandfather and great-grandfather worked in the steel mills.) One particularly notorious example of the type was James Traficant, who represented the Mahoning Valley in highly eccentric fashion and served seven years in prison after a 2002 conviction on charges that included soliciting bribes and racketeering. That left his young former staff member — Tim Ryan — to win the seat at age 29.A few stalwarts remain: Marcy Kaptur, whose mother was a union organizer at a sparkplug plant, will likely hold her Toledo-area House seat after her MAGA opponent lied about his military record. And Sherrod Brown, whose upbringing in hard-hit Mansfield and generally disheveled affect has lent authenticity to his own progressive populism (never mind the fact that he’s a doctor’s son and has a Yale degree), has survived two Senate re-elections thanks to his personal appeal and weak opponents.But nearly all the rest have vanished. Many of them fell victim to the Democratic wipeout in 2010. Others succumbed to the extreme Republican gerrymandering that followed. But central to their disappearance was the economic decline of the communities they represented, which was on a scale that remains hard for many in more prosperous pockets of the country to grasp.In the first decade of this century, after Bill Clinton signed NAFTA in 1993 and ushered China into the World Trade Organization in 2000, so many manufacturing businesses closed in Ohio — about 3,500, nearly a fifth of the total — that its industrial electricity consumption fell by more than a quarter. Mr. Ryan’s district was among the most ravaged. By 2010, the population of Youngstown had fallen 60 percent from its 1930 peak and it ranked among the poorest cities in the country.For the Democrats representing these devastated areas, the fallout was enormous. “We were always supposed to be the party of working people, and so those rank-and-file union members kept getting crushed, and jobs kept leaving, and their unions and the Democrats weren’t able to do anything for them,” said Mr. Ryan, when I met with him in August, after an event he held at a substance abuse treatment program in Zanesville. Democratic candidates were also putting their attention elsewhere, on social issues, and voters noticed.Mr. Ryan is determined not to make the same mistake. “You want culture wars?” he asks in one TV ad, while throwing darts in a bar. “I’m not your guy. You want a fighter for Ohio? I’m all in.”In the 2000s, as Mr. Ryan saw his band of like-minded Democrats dwindle, he started looking for answers, and he found some of them at the Coalition for a Prosperous America, a small advocacy group founded in 2007 to promote American manufacturing and agriculture.The group’s theory is fairly straightforward: The “free trade” that has been so ruinous to manufacturing regions like the Mahoning Valley has been anything but free, given all the various forms of support that other nations provide their own industries. The group has been lobbying members of both parties to consider explicit support for U.S. producers, whether in the form of tariffs or subsidies, even if it means brushing up against World Trade Organization rules.For years, the Coalition for a Prosperous America and its allies in Congress ran up against free-trade orthodoxy. But growing alarm over climate change, the breakdown of global supply chains during the pandemic and Russia’s war against Ukraine have brought a stunning turnaround. The Inflation Reduction Act includes many of the kinds of policies that Mr. Ryan and C.P.A. have championed, including refundable tax credits for solar-panel production, a 15 percent alternative minimum tax for corporations, and requirements that electric vehicles have North American-made parts to qualify for consumer tax credits. This month, the Biden administration announced major new tech-export controls aimed at China, with the U.S. trade representative, Katherine Tai, declaring that free trade “cannot come at the cost of further weakening our supply chains.”It’s a vindication for Mr. Ryan and his former House allies, such as Tom Perriello, who represented south-central Virginia between 2009 and 2011.Megan Jelinger for The New York Times“The elite echo chamber assumed away all the human costs” of globalization, said Mr. Perriello, instead of realizing industries needed to be helped to save middle-class jobs.Still, the shift has come only after tremendous economic losses for places like the Mahoning Valley and political losses for the Democrats. In the 2020 presidential election, Democrats lost white voters without college degrees by 26 percentage points nationwide, and their margins among working-class Black and Hispanic voters shrank, too. They lost Mahoning County, once a Democratic stronghold, for the first time since 1972.“For the most part, people lost jobs here and Washington wasn’t doing anything for them,” said David Betras, the former chairman of the Mahoning County Democratic Party. “And then Trump came along and he said, ‘Hey, they screwed you.’ People thought, ‘At least he sees me. He’s giving me water.’” It might be contaminated water, as Mr. Betras noted, “but at least it’s water.”Mr. Ryan’s attempt to point his party in a different direction in the Midwest is still running up against resistance, even as he has drawn close to Mr. Vance in the polls. The first ad released by Mr. Ryan’s campaign, in April, is Exhibit A.Wearing an untucked shirt, he delivers a barrage against the threat presented by China: “It is us versus China and instead of taking them on, Washington’s wasting our time on stupid fights … China is out-manufacturing us left and right … America can never be dependent on Communist China … It is time for us to fight back … We need to build things in Ohio by Ohio workers.”By the standards of the Ohio Senate race of 2022, it was pretty mild stuff. At an April rally with Mr. Trump, after completing his extreme pivot from Trump critic to acolyte, Mr. Vance lashed out at “corrupt scumbags who take their marching orders from the Communist Chinese.” But the Ryan ad nonetheless got opprobrium from Asian Americans, who said it risked fueling anti-Asian sentiment.Irene Lin, a Democratic strategist based in Ohio, found that remarkable. “It’s so weird that he runs an ad attacking China, and people say, ‘You sound like Trump.’ Tim’s been attacking China for decades! Trump co-opted it from us and we need to take it back, because Trump is a complete fraud on this.”Still, the episode underscored Mr. Ryan’s conundrum: how to match Mr. Trump and Mr. Vance when it comes to the decline of Ohio manufacturing without offending allies within the liberal Democratic coalition.When I asked Mr. Ryan in Zanesville how he would distinguish his own views from those of Mr. Vance, he insisted it would not be difficult. For one thing, he noted, Mr. Vance has attacked a core element of the industrial policy that Mr. Ryan sees as key to reviving Ohio: electric vehicle subsidies. At the Mahoning rallies, Mr. Vance denounced them as giveaways for the elites, which, as Mr. Ryan sees it, overlooks the hundreds of workers who now have jobs at the old Lordstown General Motors plant in the Mahoning Valley, building electric cars, trucks and tractors as part of a new venture led by the Taiwanese company Foxconn, and at a large battery plant across the street.“He’s worried about losing the internal-combustion auto jobs — dude, where’ve you been?” Mr. Ryan asked. “Those jobs are going. That factory was empty.”Mr. Ryan, left, at a debate with his Republican opponent, J.D. Vance. Mr. Ryan says his focus on economic issues will resonate with the “exhausted majority” of voters.Gaelen Morse for The New York TimesLess than two months after Mr. Ryan’s anti-culture war ad, the Supreme Court issued its Dobbs ruling on abortion, bolstering Democrats’ prospects with moderate voters of the sort who help decide elections in places like suburban Columbus — and making it harder for Mr. Ryan to avoid hot-button social issues. He calls the ruling “the largest governmental overreach into personal lives in my lifetime,” but his continued focus on economic issues shows that he believes that’s not enough to win an election. Recent polls suggest he may be right.Mr. Ryan was in the Columbus suburbs on the evening after we spoke in Zanesville, but he was there to discuss the China ad, not abortion. At an event hosted by local Asian American associations, a few women told Mr. Ryan how hurtful they had found the ad. He answered in a conciliatory tone, but did not apologize.The ad, he said, was directed at the Chinese government, not Asian or Asian American people, and the things in it needed saying. “I got nothing but love in my heart. I have no hate in my heart,” he said, but the United States needed to rise to meet China’s aggressive trade policies. In Youngstown, Chinese “steel would land on our shore so subsidized, that it was the same price as the raw material cost for an American company before they even turn the lights on. That is what they have been doing.”“That is not in your ad,” said one of the women. “You need to put those things in your ad.”“I just want to make a point,” Mr. Ryan said. “One is, I love you. Two is, I will always defend you and never let anyone try to hurt you, never. Not on my watch. But we have got to absolutely and decisively defeat China economically. And if we don’t do that, you’re going to have these countries dictating the rules of the road for the entire world and continuing to try to displace and weaken the United States.”Watching Mr. Ryan, I was struck by what a delicate balancing act he was trying to pull off. He was, on the one hand, the last of a breed, a son of steel country with two public college degrees (Bowling Green State University and the University of New Hampshire) in a party increasingly dominated by professionals with elite degrees.But he was trying to adapt to today’s liberal coalition, too, with his soft-edged rhetoric and, yes, the mindfulness stuff, which Mr. Vance has lampooned. (“You know Tim Ryan has not one but two books on yoga and meditation?” he said at the September rally with Mr. Trump.)There were other models on the ballot this fall for how Democrats might seek to win in the Midwest: Gov. Gretchen Whitmer of Michigan running for re-election on abortion rights, John Fetterman running for Senate in Pennsylvania on his unique brand of postindustrial authenticity, Mandela Barnes running for Senate in Wisconsin as an avatar of youthful diversity.But Mr. Ryan’s bid may have the most riding on it, because it is based on substantive disagreements within the party about how to rebuild the middle class and the middle of the country. For years, too many leading Democrats stood by as the wrenching transformation of the economy devastated communities, while accruing benefits to a small set of highly prosperous cities, mostly on the coasts, that became the party’s gravitational center. It was so easy to disregard far-off desolation — or to take only passing note of it, counting the dollar stores as one happened to traverse areas of decline — until Mr. Trump’s victory brought it to the fore.With its belated embrace of the industrial policy advocated by Mr. Ryan, the Democratic Party seems finally to be reckoning with this failure. It means grappling with regional decline, because not everyone can relocate to prosperous hubs, and even if they did, it wouldn’t necessarily help the Democrats in a political system that favors the geographic dispersal of party voters.It means recognizing the emotional power of made-in-America patriotism, which can serve to neuter the uglier aspects of the opposition’s anti-immigrant appeals. And it means transcending the culture-war incitements offered up by the likes of Mr. Trump and Gov. Ron DeSantis of Florida.The approach may well fall short this time in Ohio, because Mr. Ryan’s party has let so much terrain slip out of its hands. But even so, it showed what might have been, all along, and might yet be again, if a region can begin to recover, and the resentment can begin to recede.Alec MacGillis (@AlecMacGillis) is a reporter for ProPublica, an editor at large for The Baltimore Banner, and the author, most recently, of “Fulfillment: America in the Shadow of Amazon.”The Times is committed to publishing a diversity of letters to the editor.
