Mitt Romney considered a desperate, third presidential bid in 2016, aiming to stop Donald Trump as part of an unlikely unity ticket with Ted Cruz – a hard-right Texas senator who Romney privately considered “scary” and “a demagogue”, a new book reports. “Romney was willing to wage a quixotic and humiliating presidential bid if that’s what it took,” McKay Coppins writes in Romney: A Reckoning, a biography of the 2012 Republican nominee written in close cooperation with its subject. “He might even be able to swallow sharing a ticket with Cruz, a man he’d described as ‘scary’ and ‘a demagogue’ in his journal. But Romney didn’t think the gambit would actually succeed in taking down Trump. The problem was that no one else in the party seemed to know what to do about Trump, either.” Widely trailed, Coppins’ book will be published in the US next Tuesday. The Guardian obtained a copy. A spokesperson for Cruz did not immediately respond to a request for comment. Trump stormed to the nomination. Beating Hillary Clinton, he had four chaotic years in power before losing to Joe Biden. Trump refused to go quietly, however, inciting the deadly January 6 attack on Congress and now dominating polling for the next Republican nomination despite facing 91 criminal charges and an array of civil cases. Romney, now 76, is a former venture capitalist, Massachusetts governor and Winter Olympics chief executive who ran for the Republican nomination in 2008 then won it in 2012. Beaten by Barack Obama, he entered the next election as a party grandee. Describing backstage machinations by power players seeking to stop Trump, Coppins says Romney was approached five days before the New Hampshire primary by Robert O’Brien, a friend and adviser, and Jim Talent, a former senator from Missouri. “The party was in crisis,” Coppins writes. “An interloping frontrunner was on the verge of hijacking the GOP, and the rest of the field had shown they couldn’t beat him. If no one else stepped up by 1 March, they argued, Romney should enter the race and tap Cruz as his running mate to unite Republican opposition to Trump. “O’Brien and Talent called this the ‘Robert Kennedy’ strategy – get in late to build momentum, win enough delegates to keep the frontrunner from clinching the nomination, then march into the convention girded for a floor fight.” Robert F Kennedy entered the 1968 Democratic primary late, tapping a surge of support before being assassinated in California. Coppins says Romney entertained the Cruz idea, telling Talent and O’Brien his “number one priority is to stop Trump”. Formally, Romney broke with Trump after Trump refused to disavow support from David Duke, a former Ku Klux Klan leader. Quoting Romney’s journal, Coppins says he reached for the words of Winston Churchill, writing: “It is nearly certain that he will be the nominee. I am not tempted in the slightest to retreat. I will fight him on the beaches. I will fight him in the air …” In public, Romney denounced Trump in a speech, calling him a “phony” and a “fraud”. That didn’t move the needle, so Romney reportedly sought to form another anti-Trump ticket, with Cruz as nominee for president and Marco Rubio, the Florida senator also in the race, as the Texan’s running mate. That didn’t work either. The two men were “just too self-interested”, Coppins writes, adding: “With each passing day of inaction, Trump gained more votes, more delegates and more momentum.” Coppins’ reporting lands amid a 2024 primary in which a huge Republican field has again refused to coalesce round one alternative to Trump. In 2016, Romney also tried to “usher John Kasich out of the race”, Coppins writes. The former Ohio governor refused, prompting Romney to write in his journal: “Delusion runs deep in politicians’ veins.” Romney sent Kasich “a series of increasingly gruff emails”, telling him to drop out, back Cruz then fight for the nomination at the convention. Kasich, Coppins writes, responded with “more stump speech pablum”. “Refusing to believe that Kasich was so obtuse that he couldn’t grasp basic math, Romney began to entertain the theory that Kasich was somehow back-channeling with Trump. How else to explain his bullheaded commitment to a nonsensical strategy that only helped the frontrunner?” Nothing worked. Trump became president. In a move symbolic of how many top Republicans soon resigned themselves to Trump, O’Brien, the man with the Romney-Cruz plan, ultimately became Trump’s last national security adviser. Romney became a Utah senator in 2018, going on to twice vote to impeach Trump and then call him a demagogue in a stinging retirement announcement last month. But even Romney was not immune to temptation. Coppins describes a famously humiliating flirtation with becoming secretary of state after Trump won power in 2016. “Finally, Trump cut to the chase. ‘You really need to say that you’ve come to the conclusion that I’m terrific and that I’ll be a great president. We need to clear this up.’ “But Romney couldn’t bring himself to do it.”
