DESANTIS VS. NEWSOM: LIVE UPDATES

The opposing governors are known to vocalize their distaste for one another.

"To me, this is all business. I understand how this game is played," DeSantis told Fox News of his ongoing feud with Newsom in late Septemeber. "For him, it may be a little bit different.

"California and Florida just have two very different models, and we’ve seen the results of those models. People have fled California since he’s been governor. That’s never happened before. California used to be the state everyone aspired to go to. A lot of them have moved to Florida, which we never had before when I was growing up."

Newsom spoke of baiting DeSantis during a September interview with FOX 11 Los Angeles anchor Elex Michaelson.

"Of course. I mean why is he debating a guy who’s not even running for president when he’s running for president?" Newsom wondered. 

"He’s showing up at the Reagan Library, hallowed ground, and he puts out an ad today, not for his presidential campaign, to promote a debate against the governor of California. I mean, this guy’s distracted, so I don’t know that he has it in his heart. I think — here’s my personal opinion about Ron DeSantis — he regrets running for president."
