Who is number two?

I think most people who read this blog will agree that Ben Nelson is the worst Democrat in the Senate. But who is number two? There are lots of contenders. Blanche Lincoln and Mary Landrieu should make most people's short lists. How about Max Baucus, whose hearings managed to gut the health care bill and drag the process out for an extra two months, giving Republicans time to scare monger the public? Maybe a deficit hawk like Evan Bayh or Kent Conrad can make the list? The National Journal rates Bayh as the most conservative Democrat in the Senate with Nelson in the number two spot. Coming from the other side, a 2005 average of eight liberal groups rated Nelson the least progressive Democrat with Kent Conrad in the number two slot. Who do you vote for?
