Rubio isn't Jeb bad, but he's still bad. Worse than Romney, even.
No way. I'm not Diablosing, but I definitely think a lot of Dems are underestimating Rubio. Yes, the demographics are heavily in the Dems favor. Yes, Rubio will be defending shitty GOP positions. Yes, Hispanics still support Hillary by a fairly wide margin.
All that said, Rubio is young and pretty damn crafty with his answers. Watching his CNN interview over the weekend, this debate, and any other performance, he is pretty damn adept at weaseling out of a tough question and flashing a smile to deflect the questioner. Never underestimate how shallow the American public can be.
