You wouldn’t think this would be possible in our state, but two Congressman have perfect zeros on votes for supporting the troops: Jerry Lewis and John Doolittle. Down With Tyranny has great coverage and links to their progressive punch scores. This was an ad from 2006 about this issue:

Doolittle is the sicko who had party operatives send out a piece of mail the weekend before the election accusing his opponent, retired Air Force Lieutenant Charlie Brown, of being a Nazi sympathizer. Despite being in a district that is among the most lopsidedly Republican in the state (by almost 20 points!) he almost lost. It takes a special kind of chutzpah to accuse a veteran of being a Nazi sympathizer and a special kind of incompetence to blow a 20 point lead. You can contribute to Charlie Brown here. He is absolutely running again.
Dailykos, Calitics, and D-Day all have more on these two.
