Miles Taylor, a former Department of Homeland Security official in the Trump administration and the author of the new book BLOWBACK: A Warning to Save Democracy From the Next Trump (Atria, 335 pp., $30), made his dramatic entrance in 2018 with an anonymous essay for The New York Times entitled “I Am Part of the Resistance Inside the Trump Administration.” In it, he heralded the “unsung heroes” who were “working diligently from within” to impede Trump’s “worst inclinations.” The following year, having resigned from the D.H.S., Taylor published “A Warning,” also under the moniker “Anonymous.” Finally, in 2020, Taylor criticized Trump under his own name, endorsed Joe Biden and identified himself as “Anonymous.”Taylor now provides a more detailed accounting of the chaos inside the White House. Some of his allegations — that the Trump aide Stephen Miller wanted to blow up migrants with a predator drone; that the former White House chief of staff John Kelly described the president as a “very, very evil man” in response to Trump’s sexual comments about his daughter Ivanka — have made headlines and prompted some denials.The reference to “the next Trump” in the subtitle is already moot (we’re still dealing with the original one), but “Blowback” is bedeviled by a bigger problem: The more we learn of the outrageous behavior behind closed doors, the more enraging it is that Taylor — and his allies among the “axis of adults” — failed to speak out sooner. In 2018, after a particularly deranged set of phone calls about the so-called migrant caravan, Taylor told Kelly that things were getting really messed up. I wanted to shake him. Yes, Miles, it was getting pretty messed up.To Taylor’s credit, “Blowback” is full of regret. The 2018 opinion piece, while gutsy, was a sly justification for silence. By book’s end, Taylor has decided that anonymity itself, the mask he wore for years, “symbolizes the greatest threat to democracy.” The most moving passages in the book are those in which Taylor wrestles not with political monsters, but with his own demons. The mask of anonymity is entwined with his alcoholism; his recovery only arrived when he spoke truthfully in his own name. Taylor describes how falsity gnaws at the soul. Courage doesn’t always come on time, but as many an addict has ruefully remarked, it’s better late than never.The former Illinois congressman Adam Kinzinger — one of 10 Republicans to vote for Trump’s second impeachment and one of two to serve on the House’s Jan. 6 committee — is a late-breaking hero of the anti-Trump cause. RENEGADE: Defending Democracy and Liberty in Our Divided Country (The Open Field, 295 pp., $30) tracks Kinzinger’s childhood in the 1980s, his Air Force career, his six terms in Congress and his disillusionment with Trump’s Republican Party.Alas, it has none of “Blowback”’s redeeming anguish. Even Kinzinger’s sporadic insights about the roots of Trumpism (e.g. in the Tea Party) serve less to implicate the pre-Trump G.O.P. than to flatter Adam Kinzinger, who always appears presciently distressed by the intransigent drift of his own party.“Renegade” has applause lines for Kinzinger’s new liberal fans — he describes the senator and presidential aspirant Ted Cruz as an “oily, sneering manipulator” with a “punchable face” — and he adds some (unrevelatory) texture to the cowardice and bullying displayed by his colleagues. Kevin McCarthy, Kinzinger writes, behaved “like an attention-seeking high school senior who readily picked on anyone who didn’t fall in line” when he was minority leader. Twice after Kinzinger turned on Trump, he reports, McCarthy shoulder-checked him in the House chamber. (A spokesman for McCarthy has dismissed such criticism from Kinzinger as “unhinged tirades.”)What “Renegade” resembles most of all — down to its professional co-authoring by the award-winning journalist Michael D’Antonio — is a campaign book in search of a campaign. When Kinzinger announced his retirement in 2021, he said, “This isn’t the end of my political future, but the beginning.” Still, it’s difficult to imagine what sort of future that might be — unless Kinzinger gets much better at persuading other Republicans to join him out in the cold. “Renegade,” a book primarily about how much nobler Kinzinger is than his former colleagues, is unlikely to do the trick.Russell Moore’s LOSING OUR RELIGION: An Altar Call for Evangelical America (Sentinel, 256 pp., $29) is another book about a conservative suffering exile from his tribe for turning on Donald Trump.It is far more interesting, however, because Moore — the editor in chief of Christianity Today and a former bigwig in the 13-million-member Southern Baptist Convention — remains a dedicated evangelical. His “altar call” is addressed to fellow believers; to leaders of congregations riven by conflict; to pastors, like himself, whose theology is orthodox but whose politics, by Trump-era standards, are liberal; to churchgoers who’ve lost faith in their church but not in Jesus Christ. It is a startlingly open, honest and humble book, a soulful, fraternal entreaty for integrity, repair and renewal.Taylor and Kinzinger, putatively trying to convince readers to take the danger of Trump seriously, adopt a tone that is only tolerable if you already agree with them. Their books, in other words, are most likely to appeal to liberals eager for apostates from conservatism to flatter their anti-Trump indignation. By literally “preaching to the choir,” Moore, on the other hand, ironically avoids preaching to it figuratively.He is better equipped to lovingly cajole, carefully critique and persuade his readers, because he speaks to his audience in their own idiom, relying on theological concepts that hold particular potency for his fellow congregants, especially those who find themselves called to decry an evil they fear they have abetted.He is also sympathetic to the ways in which belligerent Trumpism can seduce Christian conservatives; it satisfies many of the same longings that religion does. “There is more than one way for you to secularize,” Moore writes. “All it takes is substituting adrenaline for the Holy Spirit, political ‘awakening’ for rebirth, quarrelsomeness for sanctification and a visible tribal identity for the kingdom of God.”Most of all, Moore resists the impulse to try to beat Trump at his own game. So many prophets of Trumpian doom respond to the former president’s howling narcissism with a narcissism of their own, implicitly ratifying Trump’s most noxious conceit: that he alone can fix it. But our moment calls for less heroism than humility; fewer grand self-portraits and more intimate self-searching. More
