"but how ignorant can voters be, preferring Edwards to Cheney as president?"
I share your frustration. But you have to remember that Edwards has never been targeted for national public scrutiny yet. Cheney has been for 4 years. Any reasonably pretty public figure who has never been scrutinized will poll above any experienced public figure who has been.

Isn't this a pretty sad commentary about how people make their decisions, even about such important matters, as who is going to lead our nation in a time of war?
