Is the Tea Party out to banish Bush-style conservatism?

EJ Dionne: "But imagine if the main result of the Tea Party is a "correction" of the Bush creed involving a move away from its most open and tolerant features and a rebellion against even the idea that compassion is a legitimate object of public policy. A conservatism that abandons the redeeming side of Bushism will not be an improvement on the old model."
