Marco Rubio is interesting because he checks so many boxes when you think about what a Republican nominee needs. He brings Florida, he's young, he's Hispanic, the Tea Party likes him. But that said, he's got issues, actually surprisingly, ironically, with Mexican-American voters.
Having been heavily involved in the planning of a couple of G.O.P. conventions, my view is, we should just scrap 'em. Cancel 'em. Just figure out an appropriate forum for the nominee to give an acceptance speech and be done with it.
