Donald Trump’s victory in Indiana came down quick as a guillotine—but even before the election results rolled in, the GOP faithful were jumping ship.

Former John McCain aide Mark Salter declared his allegiance to Hillary Clinton earlier Tuesday.

the GOP is going to nominate for President a guy who reads the National Enquirer and thinks it's on the level. I'm with her. — Mark Salter (@MarkSalter55) May 3, 2016

RedState blogger Ben Howe, who’s promised to phone-bank for Clinton if Trump gets the nomination, followed suit.

Once it became clear that Trump would take Indiana by a landslide, Meghan McCain and Lindsey Graham predicted the party’s altogether demise.

I guess when I said in 2012 that my party was going to evolve or it was going to die - it was easier to choose death. — Meghan McCain (@MeghanMcCain) May 3, 2016

If we nominate Trump, we will get destroyed.......and we will deserve it. — Lindsey Graham (@LindseyGrahamSC) May 3, 2016

Now more than ever, members of the #NeverTrump movement have to consider just how far they’re willing to go to see their mission through.

If this is night #NeverTrump folks go from supporting Cruz to pushing an indy candidate, remember the Texas ballot deadline is... next week. — Taniel (@Taniel) May 4, 2016

The Trump Apocalypse may not come to pass, but the Republican Party is already preparing for doom.
