Rubio is a doofus. Obviously not ready for prime time and he is ineligible anyway.
Think of how many clumsy things Obama has done. Also, think of Reagan’s gaffes. It’s how you handle them and what else you do that is memorable in a positive way that matter. The question is what is Rubio going to do next? I heard on the radio today that he poked fun of himself on Twitter or Face book or something, with a picture of an empty water bottle. So he is trying to recover.
