Exactly. We hear the hysterical "brokered convention" talk every cycle and it just isn't likely to happen.
If Newt continues improving as a candidate and wins the nomination, the "establishment" will fall in line. They may fight him all the way, but if Gingrich proves too strong to stop, the folks complaining about him will just change their tune and declare he's grown as a person and a candidate.
Unfortunately, several of the republican elites and know-it-alls are in control of PACs with lots of bucks, like Rove. I'm not so certain they will fall in line and release the money unless the nominee is Romney.
I hope my suspicions are wrong.
