Trump drew conservative criticism almost immediately after announcing his presidential candidacy in June 2015. Writers at the National Review made opposing Trump an editorial policy, with contributor Jonah Goldberg warning that Trump's supporters were "being conned and played"10. Mona Charen, also writing for the magazine, called Trump "a blowhard with all the nuance of a grenade"10. Early objections focused on Trump's departures from Republican orthodoxy: his past support for single-payer healthcare10, his pro-choice history, his advocacy for an assault weapons ban, and his donations to Bill and Hillary Clinton's campaigns and foundation10.

The crowded Republican primary field, which at one point exceeded seventeen candidates, divided traditional conservative voters and let Trump win early contests despite polls showing a majority of Republican voters would have preferred another nominee15. Super Tuesday exit poll data from states like Arkansas and Virginia showed that more voters would have been satisfied with a Rubio or Cruz nomination than a Trump nomination, but the split field kept handing Trump victories15.

On February 26, 2016, the hashtag #NeverTrump began trending worldwide on Twitter1. The immediate trigger was Trump's commanding victory in the Nevada caucuses, compounded by New Jersey Governor Chris Christie's surprise endorsement4. The hashtag caught fire across partisan lines. Presidential candidate Marco Rubio shared a link encouraging supporters to add their names to the cause, and conservative commentator Erick Erickson tweeted that he was "proud to play a role in getting #NeverTrump trending"1.

The #NeverTrump movement marked a rare moment of organized, public rebellion within a major American political party during a presidential primary. It generated heavy coverage from outlets across the political spectrum, with the Washington Post, New York Times, Fox News, CNN, and NPR all dedicating substantial reporting to the movement's trajectory716.

The movement's failure to stop Trump's nomination, and his subsequent general election victory, reshaped how political commentators discuss intra-party opposition. The Cook Political Report's pre-election analysis noted Trump's "historic unpopularity with wide swaths of the electorate," including women, millennials, independents, and Latinos, but those weaknesses weren't enough to prevent his win22.

The Lincoln Project, a direct outgrowth of the 2016 movement, produced viral attack ads targeting Trump and Republican senators like Lindsey Graham in the 2020 cycle. The group's ad portraying Graham as a "parasite" feeding off Trump drew significant attention but also criticism from the right17. 60 Minutes aired a segment on the Lincoln Project, and the New Yorker published a 7,300-word profile of the organization17.

Erick Erickson's push for a third-party alternative in 2016 foreshadowed ongoing debates about whether the Republican Party could sustain a coalition that included both Trump's populist base and traditional fiscal and social conservatives7. The movement also exposed the gap between Republican voters and the party's donor and commentator class, a dynamic that Jindal acknowledged when he wrote that "we have failed to convince or demonstrate the wisdom of our conservative policies to the voters, and we are thus partially responsible for the rise of Trump"23.

The #NeverTrump movement reached its crisis point on May 3, 2016, when Ted Cruz dropped out of the Republican primary after losing Indiana. RNC Chairman Reince Priebus declared Trump the presumptive nominee and called on Republicans to "unite and focus on defeating" Hillary Clinton14. For many in the movement, this was exactly the scenario they had dreaded, and reactions split along predictable lines.

Some Republicans capitulated. Former Arkansas Governor Mike Huckabee went "all in" for Trump, dismissing the "#NeverTrump nonsense" and telling holdouts: "This isn't Burger King. You don't get it all the time just like you want it"18. Bobby Jindal, who had once mocked Trump in some of the harshest language of any primary candidate, endorsed him while calling it the "second-worst" option available21. Jindal's op-ed was notable for its blunt framing: "I am not pretending that Mr. Trump has suddenly become a conservative champion or even a reliable Republican. He is completely unpredictable"21.

Others dug in harder. Erick Erickson called for a third-party candidate to give disenchanted Republicans a reason to show up at the polls and protect down-ballot races7. In an NPR interview, Erickson argued that roughly 40% of Republican voters would refuse to support Trump, and without an alternative on the ballot, congressional and state legislative races would suffer catastrophic losses7. Over at the Washington Free Beacon, journalist Lachlan Markay burned his Republican voter registration on camera5. Former John McCain staffer Mark Salter and RedState blogger Ben Howe declared grudging support for Hillary Clinton5.

Weekly Standard editor Bill Kristol emerged as the most visible organizer for a third-party alternative. In early May, he met privately with Mitt Romney at the J.W. Marriott hotel in Washington to discuss an independent presidential bid19. "He came pretty close to being elected president so I thought he may consider doing it," Kristol told reporters, adding that he also wanted Romney's endorsement for any alternative candidate that might emerge19. Kristol had also courted retired Marines Corps General James Mattis, who declined to run19. At a public event afterward, Romney told attendees: "I am dismayed at where we are now. I wish we had better choices"19.

The electoral math painted a grim picture for Trump at the time. A CNN/ORC poll completed before Trump's Indiana victory showed Clinton leading 54% to 41%, her largest margin since July 20158. Both candidates were historically unpopular, with 56% of voters viewing Trump unfavorably, and most supporters of each candidate saying their preference was driven more by opposition to the other side than genuine enthusiasm8. The Cook Political Report shifted ratings in 13 states toward Democrats, placing enough electoral votes in the "Lean Democratic" column for a Clinton majority before the general election campaign even began22.

The movement's organized wing struggled with money after Indiana. Anti-Trump groups had spent $2.8 million in the state, plus an additional $3.3 million backing Cruz, yet Trump won decisively3. Rob Stutzman, a California strategist organizing stop-Trump efforts, admitted that "Indiana will influence our fundraising" even before the results came in3. California's June 7 primary, with its 172 delegates, was supposed to be the movement's backstop, but Trump needed fewer than 200 additional delegates to clinch, making the math nearly impossible3.

Within the movement, a counter-hashtag emerged. #NeverHillary was adopted by conservatives who, while unhappy with Trump, viewed Clinton as the greater threat24. Fox News commentator John Gibson urged NeverTrumpers to "come to your senses," arguing that stopping Clinton should take priority over internal Republican disputes24. Jindal's CNN opinion piece acknowledged that the Republican establishment bore some blame for Trump's rise, arguing that the party "failed to convince or demonstrate the wisdom of our conservative policies to the voters"23.

The NeverTrump identity persisted well beyond 2016. By 2020, the Lincoln Project, founded by Republican operatives including Rick Wilson and Steve Schmidt, was spending tens of millions on anti-Trump advertising17. Bill Kristol's Defending Democracy Together organization, funded in part by Pierre Omidyar, operated several anti-Trump outlets including The Bulwark and Republican Voters Against Trump17. Critics on the right dismissed these groups as grift operations, noting that most of the Lincoln Project's nearly $40 million in third-quarter 2020 fundraising came from left-wing donors rather than disaffected Republicans17. Trump won the 2016 election despite the movement's efforts, and the term "NeverTrumper" became a fixture of American political vocabulary, used as a pejorative by Trump supporters and as a badge of principle by holdouts.
