Rush Limbaugh, this morning (which the Rubio camp is, understandably, sending around):

I like Rubio

In the Republican Party particularly, there is a fatigue with RINOs and moderate Republicans…

Republicans, the only chance they have of winning national elections is to go conservative, I think that’s what’s brewing out there, and the Republican Party is going to be looking at this Crist-Rubio primary because it is going to be a pretty stark contrast.

…

I noticed that Crist is out there now hey what do you mean, who says I’m not conservative, I’m pro-life, I’m pro gun, I don’t know what more I have to be except angry…that’s not going to sit well.
