Where is the GOP bench? Where are the rising stars in the party? I don't see any. We are in big heap of trouble (a little Indian lingo there). Other than Arnold, who cannot run for POTUS, what other GOP governors are out there that can be viable Presidential candidates? Forget about Senators, a Senator will never be elected President again.
The only 'name' out there that is not a Senator is ole Rudy. Who is far too liberal socially for the base methinks. But if he is paired up with a conservative running mate it may be stomachable to conservatives in the general election.
If he survives the primary though is another question. Though the fear of Hillary may be enough to get conservatives to vote for him. I would cast a ballot for him in a heartbeat (and I despise RINOs) if it came down to him vs. Clinton (who already has had two terms as POTUS ;) ).
