America's domestic enemies must be laughing at the comment that a republican "doesn't have enough experience to step in as President". It takes a lot of chutzpah for any Obama supporter to attempt that line.
NBC is a different issue, and Rubio is not NBC since his parents were not citizens when he was born. I will not under any circumstances vote for a Rubio ticket, and I will to the best of my ability avoid contributing to anything an administration with Rubio wants to accomplish.
