I do believe Newt and Romney are working the delegates and began doing so some time ago....as well as those who appoint those delegates. Sanatorium simply doesn't have the manpower nor connections strong enough to do so. Especially since he was the diversion away from Newt.
Am still hopeful Newt and Sanatorium can remain in this long enough to get to convention....the delegate card have not yet been played....candidates can fight the bound and unbound distribution of candidates as well.
Although I'd love to see Sanatorium drop out and give Newt the reins to take this all the way to convention. Ricks had his two man race and has failed thus far to stop Romney. So he cannot blame Newt any longer for his failures.
If we go to a brokered convention, which is increasingly unlikely, we will have chaos.
Gingrich is good at being a bombthrower. That's how he's made his career, and I don't necessarily have a problem with that. However, I definitely see why it frightens the Republican establishment, just as the possibility of a 2008 brokered convention frightened the Democrats.
