2 and 3 cannot happen without a major faceplant by Romney. He will have too many delegates at Tampa who will be required/desire to vote for him on the first round. The women with baseless sexual harassment charges will not be trotted out until after he safely has the nomination.
Rats. I doubt he'd endorses Newt. He's bought and paid for now.
LOL! You pretty much go that right!
But, you know a delegate chase is worth a try.
