Americans for Tax Reform’s famous Taxpayer Protection Pledge took some fire this week from Sen. Saxby Chambliss. ATR head Grover Norquist fired back, saying that violating the pledge isn’t a break from Grover or ATR, but from the voters in Georgia to whom he’ll have to answer.

Though almost every House and Senate Republican has signed the pledge at some point in their career, more and more Young Guns are taking a pass. Old Guns are weighing in, too. When asked about Norquist and his pledge this summer, George H.W. Bush quipped, “Who the hell is Grover Norquist anyway?”)

Will ATR’s pledge survive the fiscal cliff? What about political pledges in general? If you were running for office, would you sign ATR’s? Would you sign any?
