Ted Cruz is the dark horse of the possible nominees. Alot of people are writing him off already, but that's a very unwise assumption to make.
He's a Harvard Law graduate and the leader of the debate team while he attended. That explains why he's unafraid to go on CNN and MSNBC and take tough questions, and he's left each appearance nearly unscathed, and put some media figures on notice of his potential.
Harvard Law Professor Alan Deshowitz praised Cruz as one of the smartest students he's ever had.

Even George Carville had this to say about Cruz, who isn't known for praising those on the opposite side of the political isle.

It's worth noting Carville said this only 5 months after becoming a Senator.
And Cruz has already entered a political election as a severe underdog to eventually win his Senate seat. Months before the Nov'10 election he only had 2% in the polls, against an opponent who was the Lt. Governor at the time, who was endorced by practically everyone in the state who's endorcement was worth anything, and with a much deeper fundraising war chest.
Am I saying that it's enivitable that Cruz is going to beat everyone else in the running for the nomination? No. I'm merely saying that it's unwise to write him off as others have in the media, which seems like it's more wishful thinking.
