In a radio interview on Monday, the hard-right columnist Ann Coulter said she wouldn’t vote for Donald Trump if he doesn’t build his promised border wall. “They’re about to have a country where no Republican will ever be elected president again,” Coulter said. “Trump will just have been a joke presidency who scammed the American people, amused the populists for a while, but he’ll have no legacy whatsoever.”

When news of Coulter’s criticism aired, Trump or someone who handles these matters for him seems to have unfollowed Coulter on Twitter:

Coulter said "Trump will very likely not finish his term and definitely not be elected to a second term." Fox cited her comments around 7:05. Then this... https://t.co/KOhqaHIPDc — Brian Stelter (@brianstelter) December 20, 2018

This isn’t the first time Coulter and Trump have had a split. In August 2016, then-candidate Trump flirted with a more moderate immigration stance, including amnesty for undocumented immigrants. Coulter on a dime turned fiercely anti-Trump and started lambasting him as soft on immigration.

It's not "amnesty." It's "comprehensive immigration reform"!!!! Trump: "they have to pay taxes, there's no amnesty." — Ann Coulter (@AnnCoulter) August 25, 2016

Trump: "they have to pay taxes, there's no amnesty" [Pro Tip: "Back taxes" means we pay illegals $30k apiece in EITC.} — Ann Coulter (@AnnCoulter) August 25, 2016

Coulter’s barrage of criticism in 2016 actually had a positive impact from her point of view: Trump quickly gave up moderation and returned to his nativist stance. Coulter worked as an effective enforcer of ideological rectitude. Perhaps that’s her goal now as well.
