I don't have a strong opinion of the guy at this point, but how absurd is it that Wolf Blitzer asked if Rubio taking a drink of water during his speach was a "career ender."? Almost nothing on the substance of the speach. Joe Biden is more gaff prone then any politician in history yet his credentials are never questioned. And people try and say with a straight face that there is no media bias.
Unlike some, I actually get my news from a variety of sources - I prefer papers and periodicals to TV. I really don't like Hannity - He's an intellectual lightweight and his show is generally about antagonizing his guest. I don't like Beck either.
But based on his ridiculous comment on Rubio, you're right in questioning why in the world anyone should watch him.
