I think you are overly pessimistic. The moderators will have their long knives out and the majority of the “folk” may be ringers, but Romney’s team trained him well.
The core of Bobo’s debate problems stem from his narcissism. He has NEVER had anyone talk to him like that Romney did. I predict that he will become so frustrated that he will have some kind of embarrassing melt-down.
Then there also is the courageous Israeli Prime Minister who displayed the qualities of an authentic leader in forthright remarks to the President while seated beside him in the White House press conference.
The reactions were similar, however.
My worry is that the town hall debate will be wall-to-wall abortion and gay marriage, with a little 'war on women' thrown in for good measure.
Unless Romney is really on his game, look for the moderator and the "folk" to kneecap him on the social issues while they circle the wagons around Zero.
