If I was voting in a Republican primary today, I would vote for Newt Gingrich. Last year I voted for Mitt Romney because, for one reason, Gingrich wasn't running.
This article has a bit of a recap of Newt's speech at CPAC a couple of weeks ago and it appears as if he is sending signals that indicate he's running in 2012.
If Obama still can't find enough clean Democrats to fill his Cabinet by then, and if he continues his wealth destroying policies, then he could be beaten by a sock puppet.
Fortunately, Gingrich has more going for him than that. He just might not need it.
