Presumptive GOP presidential nominee Donald Trump spent a part of this week in Washington, D.C., trying to shore up support among members of the Republican establishment—a clear sign that one of the most divisive candidates in history has realized the backing of his party is crucial to his ultimate success. But while Paul Ryan, the speaker of the House and the most powerful member of his party, last Thursday said he is “just not ready” to support Trump, and others coalesce around a “Never Trump” doctrine, it appears that the fight against him will go on—even if there’s no one else to vote for.

The “Never Trump” movement is large and diverse, and has been gaining steam for quite sometime. The movement was popularized in January, when the conservative-leaning National Review magazine released an edition whose cover spelled out in gilded letters, “Against Trump.” Inside, prominent conservatives and anti-establishment media stars spelled out their cases against the straw-haired tycoon and laid into Trump’s politics.

When Trump was left the last candidate standing earlier this month, two major anti-Trump PACs immediately declared that they will continue to bat against the billionaire mogul’s campaign. The biggest one, Our Principles PAC, said it would try to force a contested convention this July in Cleveland as long as Trump still falls short of the 1,237 (he’s currently at 1,134), while a senior advisor to the Never Trump PAC, sat down with MSNBC recently and assured the network that “never still means never.” Additionally, as of Saturday, almost 38,000 people have signed the #NeverTrump pledge.

While high-profile Republicans have professional reasons for opposing Trump, the party’s rank and file is a different story. In order to gain a better understanding of those in the GOP rank and file that despise their future candidate, Vocativ aimed to break down the anatomy of the anti-Trump movement.

Take the #NeverTrump Facebook page, the largest of its kind: a Vocativ analysis of the page, with over 2,900 members, maps out a relationship web, by looking at what other pages people like—and shows the unusual breadth of the opposition. Fans of conservative pundit Glenn Beck and the National Review can be found in the web, as can Fox News viewers and supporters of Trump nemesis Megyn Kelly.

But what comes out of this apparent unity? One of the Facebook page’s administrators, Matthew Kreska, said the #NeverTrump page originally was started as a place for GOP members to gather and discuss politics. However, as the primaries proceeded and Trump clinched victory after victory, the group switched gears as a front against The Donald. “More it seems that the #NeverTrump movement is a consensus by a large number of Conservatives and Republicans (and later also Democrats & Liberals) who outright reject Donald Trump, his approach, and his stances,” he told Vocativ in an email.

With slim pickings now in the Republican field, Kreska said he remains firmly against Trump and is looking to popular Libertarians such as Gary Johnson and Austin Petersen to throw his support behind. “I don’t see any situation in which I could support Trump. Nor do I see a case where I would settle for Trump as an alternative to the candidate from the left,” he said, adding that Trump’s political showmanship, brashness, and willingness to essentially blow up the system leave little room to reconcile.

The movement also lives on sites such as Reddit. The Never Trump subreddit, which counts roughly 1,100 subscribers, describes itself as a “gathering place for those looking to put up a fight against [Trump’s candidacy].”

User RebasKradd, one of the page’s moderators, said that the movement originally started as a sort-of support group for Ted Cruz but has since morphed into a space to debate the future of conservatism and the Republican Party. “Betrayed conservatives are actually the heart and soul of #NeverTrump, regardless of what Trump supporters say,” the user told Vocativ in a Reddit direct message. “We value decency and principles, neither of which Mr. Trump has demonstrated during his campaign.”

However, RebasKradd admitted that it’s difficult to build any sort of faction around an opposition to something rather than in support of it. “But with the right people, we’ll manage,” the user wrote.
