edit: In 2012, sorry....
Personally I would like to see Governor Piyush "Bobby" Jindal: youth, energetic, strong core values, mainstream GOP base covered. Also, a Mike Huckabee would be a close 2nd if Jindal wasn't running. Although Romney would be great as well as Dr. Ron Paul, Mitt is just a CEO say anything to get x, y, and z, and Paul is just to far out for the GOP of today.
Your thoughts? 3rd parties are welcome too.
