Once upon a time, this list, Top 10 Dumbest Politicians in Amercia, was the definitive list of really stupid politicians. That original link is now broken. I guess the webmaster of that site, if he were a politician, would be on the lists below.
Now, I think the list has grown to 535.
Here are two lists. Taken together, they form the definitive list of the dumbest people in America.
Regrettably, Sarah Palin is not on either list. She is, perhaps, the dumbest politician to have emerged from an emu's ass in decades.
