Tonight’s presidential debate in Mesa, Arizona, is rightly be touted as a crucial moment in the Republican race. Much has changed in the weeks since the GOP candidates were brought together in front of the television cameras. Rick Santorum, whose strong showings in the Florida debates were not thought to signify any real hope of his being the nominee, is now leading in the national polls. Mitt Romney, who was hoping to create an aura of inevitability, is now struggling to stay ahead of Santorum in his home state of Michigan, and Newt Gingrich has sunk to last place in some surveys and must fight the belief he no longer has a ghost of a chance of victory.
But while Santorum will enjoy being in the center of the stage rather, as up until now he has been relegated to the sides, he will also have to cope with being the object of attacks from both Romney and Gingrich in a way that he has never had to deal with in the many debates that have preceded this one. While all the participants, save Ron Paul, have something to prove tonight, the outcome may turn largely on one question: which Rick Santorum shows up in Mesa? Will it be the confident, relaxed and personable Santorum who has done so well in the previous encounters and whose image is as a caring father and clean politician who is not willing to engage in mudslinging? Or will it be the angry culture warrior whose obsessions with gays, contraception and abortion have become the liberal caricature of conservatism in the last week?
