I'm sensing more panic today than on the SC or NV election nights. Friend who worked for Jeb said the feel about last night was that Rubio did what he had to do and the endorsements were coming. Well the endorsements are still coming but Christie has people panicking due to the validation he gave Trump, and the potential for more from desperate officials.
Trump and Christie are destroying Rubio on some personal levels, this is insane. And given that Trump is probably going to sweep the south he could bury Rubio. I'm guessing the endorsements will come immediately after Super Tuesday. McCain, W, HW, etc.
They'd have to, Rubio wouldn't be able to survive a loss in Florida. If he's going to be the guy he'll need a win.
