The Republican convention that nominates Donald Trump for a second term will be the greatest event in the political history of cancel culture. What Trump is cancelling is nothing less than the Republican party as it has existed before him. He ran in 2016 in the primaries on cancelling the GOP and in 2020 he ratifies his triumph. After the election, political scientists and historians will study his obliteration of the Republican party as his greatest and most enduring political achievement.The Republican party has been on a long journey away from being the party of Abraham Lincoln, accelerating since Barry Goldwater and rightwing cadres captured it in 1964 in reaction to the civil rights movement. After Richard Nixon embraced the southern strategy and won the nomination in 1968 with the help of Senator Strom Thurmond of South Carolina, the Dixiecrat segregationist presidential candidate in 1948, the party increasingly radicalized in every election cycle and became gradually unmoored. In 1980, Ronald Reagan opened his general election campaign at the Neshoba County Fair, the place where three civil rights workers had been murdered in 1964. Surrounded by Confederate flags, he hailed “states’ rights”. As brazen an appeal as it was, Reagan felt he had to resort to the old code words.Central to Trump’s unique selling proposition is that he dispenses with the dog whistles. His vulgarity gives a vicarious thrill to those who revel in his taunting of perceived enemies or scapegoats. He made them feel dominant at no social price, until his catastrophic mismanagement of the coronavirus pandemic and economic crisis. Flouting a mask is the magical act of defiance to signal that nothing has really changed and that in any case, Trump bears no responsibility.But there has also been a political cost to Trump’s louche comic lounge act that still transfixes a diehard audience lingering like late-night gamblers for the last show. Trump is the only president since the advent of modern polling never to reach 50% approval. Despite decisively losing the popular vote in 2016, he said he “won the popular vote if you deduct the millions of people who voted illegally”. This time, fearing an even more overwhelming popular rejection, he says the outcome will be “rigged” and he has pre-emptively tried to cancel the US Postal Service, to undermine voting by mail.From Reagan onward, even as the fringe moved to the center and took it over, the party did not anticipate that it was slouching toward Trump. Conservatives have consistently failed to grasp the unintended consequences of conservatism. Even when Reagan fostered the evangelical right, George HW Bush appointed Clarence Thomas to the supreme court, George W Bush invaded Iraq and neglected oversight of financial markets that collapsed, and John McCain named Sarah Palin as his running mate, Republicans believed they were expanding the attraction of the conservative project. When Newt Gingrich, Roger Ailes and Rush Limbaugh methodically degraded language, it seemed a propaganda technique to herd supporters. When the dark money of the Koch family and the wealthy reactionaries of the cloaked Donors Trust bankrolled the lumpen dress-up Tea Party to do their bidding on deregulation of finance and industry, the munificently funded conservative candidates did their bidding as retainers of privilege.In the wasteland, only cockroaches and Mitch McConnell may surviveAt the presidential level there still remained residual elements contrary to what metastasized into Trumpism. Reagan represented free trade and western firmness against Russia. George HW Bush was a paragon of public service. George W Bush was an advocate for immigrants. John McCain was the embodiment of patriotic sacrifice.After Trump, all that has been cancelled. Since he first rode down the escalator at Trump Tower in 2015, to declare his candidacy against Mexican “rapists”, there has always been a new escalator downward. After overcoming his initial hesitation, the House Republican leader, Kevin McCarthy, welcomed the election of a QAnon conspiracy-spouting candidate from Georgia, Marjorie Taylor Greene. Then McCarthy condemned QAnon and stated that Greene wasn’t part of a movement she continued to defend.Trump hailed her as a “future Republican star”. For months, he has been tweeting messages to encourage the racist, antisemitic cult. “There’s a once-in-a lifetime opportunity to take this global cabal of Satan-worshiping pedophiles out, and I think we have the president to do it,” Greene proclaimed. “I’ve heard these are people that love our country,” Trump said. In the wasteland, only cockroaches and Mitch McConnell may survive.Stuart Stevens, a prominent Republican political consultant, eyes startled wide open, has entitled his exposé of the party It Was All A Lie. He describes the conservative Trump apologists, the adults in the room, as latter-day versions of Franz von Papen, the German chancellor who enabled the rise of Hitler in the complacent belief that he could be controlled and the conservatives would maintain power.On 4 July, at the mammoth stage set of Mount Rushmore, Trump mugged for his photo op by posing his face next in line to the carving of Abraham Lincoln. He had earlier told the South Dakota governor, Kristi Noem, “‘Did you know it’s my dream to have my face on Mount Rushmore?’” “And I started laughing,” she recounted. “And he wasn’t laughing, so he was totally serious.” (Trump tweeted that it was “fake news” that he had ordered an aide to inquire about immortalizing his face on the mountain.)Ostensibly, Trump came to deliver his ideological message. He denounced “cancel culture”, which he said was “the very definition of totalitarianism, and it is completely alien to our culture and to our values, and it has absolutely no place in the United States of America”. He attributed it to “a new far-left fascism”. And he spelled out its punitive nature: “If you do not speak its language, perform its rituals, recite its mantras and follow its commandments, then you will be censored, banished, blacklisted, persecuted and punished.” Thus, he offered a concise description of his own cancel culture’s methods.Trump’s cancel culture deals in aggressions, not micro-aggressions. The only safe space is where Trump is worshipped. Before, during and after the death of McCain, Trump unleashed tirades of insult. He finally complained that the McCain family never thanked him for approving the senator’s funeral arrangements, even though it was Congress that gave approval. For years, Trump has disparaged the Bush family. At the onset of the coronavirus pandemic, when George W Bush called for setting aside partisanship and embracing national unity, Trump tweeted, “but where was he during Impeachment calling for putting partisanship aside”.Trump’s cancel culture deals in aggressions, not micro-aggressions. The only safe space is where Trump is worshippedTrump has invoked Reagan only as a stepping stone of his own monumental pedestal. At a rally in 2019, Trump mused: “I was watching the other night the great Lou Dobbs [of Fox News], and he said, ‘When Trump took over, President Trump,’ he used to say, ‘Trump is a great president.’ Then he said, ‘Trump is the greatest president since Ronald Reagan.’ Then he said, ‘No, no, Trump is an even better president than Ronald Reagan.’ And now he’s got me down as the greatest president in the history of our country, including George Washington and Abraham Lincoln. Thank you. We love you too.”When Trump sought to profit for his 2020 campaign by selling a gold-colored Trump-Reagan commemorative coin set, the Reagan Foundation sent him a curt letter, telling him to cease and desist. Trump has constantly retailed a false story about Reagan supposedly remarking after meeting him, “For the life of me, and I’ll never know how to explain it, when I met that young man, I felt like I was the one shaking hands with the president.” The chief administrative officer of the Reagan Foundation felt compelled to note that Reagan “did not ever say that about Donald Trump”.
