Charles Krauthammer blasted Sen. Ted Cruz for not endorsing Donald Trump on Thursday, arguing that it “the longest suicide note in American political history” because it “destroyed his political career.”

Appearing on Fox News’ “America’s Newsroom,” Krauthammer said, “Well, last night what Cruz delivered was the longest suicide note in American political history. And this morning he add an addendum because last night, the theme of it was, that as a matter of principle, as a conservative, as a constitutionalist he could not endorse Donald Trump.” (RELATED: Cruz Booed For Not Endorsing Trump At GOP Convention [VIDEO])

And then he blew it,” Krauthammer said. “You could see him, it was towards the end of this event. He was asked a question about endorsing and he said, you can see him calculating, should I really give the reason. And then he said this is all personal.” (RELATED: Trump: Cruz Betrayal Is ‘No Big Deal’)

“It’s about the wife and the father. And then what that does is he’s a calculating guy,” Krauthammer argued. “What that does is it totally undid the great political philosophical reasons he offered last night. That was already in jeopardy because remember for the first six months of the campaign he was especially nice to Trump. He was drafting in the wake of the head car and everybody else was attacking Trump over the McCain comments and he didn’t. So this was not a matter of principle, it was already in question as of last night but as of this morning I think he’s destroyed his political career right there.” (RELATED: Eric Trump Blasts Cruz’s Convention Speech As ‘Classless’ [VIDEO])
