In his book, Ship of Fools, Tucker Carlson does a timeline on Kristol’s position on Trump
Tucker shows that for a time during the 2015-16 campaign season Kristol was not hostile to Trumps candidacy. But that changed overnight with the South Carolina primary debate. At that debate, Trump sharply criticized Bush’s invasion of Iraq. Suddenly, as Tucker writes on p 117, “Kristol erupted.

The origin of the nevertrump movement was all about the Iraq war - or rather, Trump becoming the first major GOP candidate to condemn it
