How about Pence?
Pence is just about the only speculated candidate I would support over Palin right now. It will be interesting to see if he can put together a viable campaign coming from the House. Maybe Jindal if he ran. I think either one of those guys would campaign and govern as Reagan conservatives plus they would pound Obama in the general election. I also like Bob McDonnell but I think it is probably one cycle too early for him.
