Senator Fred Thompson will bomb, and cause his supporters to seriously reconsider support for his candidacy.
Mayor Rudy Giuliani will excel, and demonstrate a commanding leadership presence.
Senator John McCain will again forcefully articulate why we must achieve victory in Iraq, and get no bounce in the polls.
Governor Mitt Romney will deliver a smooth and polished answer every time, but still leave the audience and primary voters wondering exactly what he believes.
Rep. Ron Paul will do his Rain Main impersonation, which will again send the white coats running for his supporters. Definitely. K-Mart sucks. R-O-N-P-A-U-L. R-O-N-P-A-U-L. Main man.
Gov. Huckabee, Rep. Hunter, Sen. Brownback and Rep. Tancredo will be non-factors.
In short, the conventional wisdom prevails and the debate will have no significant impact on the campaign.
