To prove that Dean was not "just talking about GOP leaders" when he said a lot of them have not worked an honest day in their life, simply point out the context--Dean was saying that voting in one day only might be good enought for Republican voters because a lot of them have not worked an honest day in their life; but Democrat voters have to go to work and it is simply too inconvenient for them to vote if Election Day is only one day.
Hmmmmm! What king of doctor was he????
