If we're talking about those who would hop off a cliff for 0bama, I'd revise that figure upward to 40%. Between that and whomever else he can bamboozle into staying the hopenchange course, I'd estimate his guaranteed support level will be about 48-49% in 2012.
From your lips to the ears of whoever is running the 2012 campaign for the Republicans.
I honestly believe even if things get a lot worse we are going to have to fight tooth and nail to get that socialist sonofabitch out of the White House. The idea that "anybody" will be able to beat Obama is both naive and delusional.
