It's funny that the poll only gives us: George HW (read my lips) Bush; Clinton, George (Compassionate Conservative) Bush, and Barack (you can keep your doctor) Obama.

Even some rabid Obama supporters used to be Reagan democrats. They still like Reagan even though their brains are now mush. Their judgement is based on shallow TV viewing and Clinton is much more likable than Obama.
