Ann Coulter and Donald Trump part ways, again.

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:

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.

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.
