Republicans have a bit of a problem on their hands when it comes to motivation. Neocons think scaring people to the polls is the best idea. Tea Partiers want a fresh face in Washington. Fiscal Conservatives are more worried about the budget.
There really is a deep crack down the party. I'd say Palin and Jindal are out. They may run, but they won't win. Huckabee doesn't have a message that resonates with the entire country, just the mid-west and south. If I had to guess right now I'd say Romney would be the front runner from the GOP. Someone who hasn't been in office for a while (so you can't pin any of the recent problems on him). He's also laid kind of low and not been out in the open making stupid comments like Palin about drilling.
Right now I'd say Romney...with neocons/social cons scaring their voters enough to forget about him being a Mormon.
i would take a death dumb quadriplegic president over the existing one... but to be fair its less to do with him specifically and more to do with i don't want 95% of the legislation that we are pushing for
