During the Republican primaries, Joe Scarborough’s favorite object of ridicule was Marco Rubio. Scarborough dismissed Rubio as a “school council president,” called him the “emptiest of suits,” and attacked his supporters.

In a particularly personal shot, Scarborough devoted much of a show to mocking Rubio’s wearing of boots with large heels.

But suddenly, Scarborough has become a huge Marco admirer. On today’s Morning Joe, Scarborough repeatedly praised Rubio and his “courage.” So what shifted Scarborough from Rubio antagonist to fanboy?

Simple: Rubio, in tweets and elsewhere, has sharply criticized President Trump by name for his remarks about Charlottesville. The enemy of my enemy is my friend. Or in Joe’s case, his hero.

JOE SCARBOROUGH: I’ll just say: Marco Rubio, in the forefront. If every Republican would show the courage that Marco Rubio’s showing right now, I think the Republican party might even be okay . . . You’ve got to be courageous enough to do, I said Marco, but John McCain, several others . . . Again, look at Marco Rubio’s tweets . . . I talked about Marco Rubio, I saw a tweet Marco Rubio, in February of last year, saying we can’t, basically we can’t elect a racist.
