Rubio on CNBC this morning

Senator Rubio is on CNBC this morning.  Joe Kirnan just remarked that he can't wait to see Rubio debate Biden (if Rubio is tabbed by Romney for the VP slot).  It would be a 1st round knockout.  Joe's right, but I don't see any way that Obama's campaign would allow Biden to debate on tv against someone who would so clearly destroy him and expose him as a fool.
