I think you overestimate Rubio’s chances... after Saturday’s debate, he’s basically become a punchline... Can one recover from a punchline? Sure, if you are a punchline early enough in the process and given enough time... 19 days isn’t a whole lot of time.
Rubio literally shot himself in the head last Saturday, it truly was spectacular to see someone do that, no I’m not speaking hyperbole, it was literally a political Bud Dwyer moment. The exchange with Christie will be studied by political science students for decades hence.
So far as I know no new SC polls have come out since then, but I just don’t see how Rubio sees more than 10% or so again. He had his moment and chance coming out of IA, and he just blew it.
I so hope you are correct
