Many observers see Barak Obama as another Jimmy Carter, and the parallels are remarkably strong. Both are (were) outsiders, untested, lean left, promise a fresh face, plan to shake up the status quo, inexperienced internationally and want government to be more activist.
By some measures, Carter was one of the worst presidents ever. His liberalism at home and abroad actually so turned people off that he ushered in Reagan conservatism.
Today many true conservatives, as opposed to Republicans, actually see merit in four disastrous years of Obama, as it would revive true conservatism.
