Ben Nelson - 42%

Think selling your soul doesn't carry a steep price?

Nelson, who once enjoyed some of the highest job performance marks in the U.S. Senate, has now seen his approval rating dip below 50 percent in Nebraska, according to The World-Herald Poll. …

In the survey, Nelson’s job approval rating was 42 percent and his disapproval rating was 48 percent. By comparison, Republican Sen. Mike Johanns of Nebraska, who voted against the bill, had a 63 percent job-approval rating. …

It’s clear the bulk of Nebraskans’ dissatisfaction with Nelson rests with his health care vote.

More than 60 percent of those surveyed said they opposed the Senate health care bill. A majority said they opposed Nelson’s vote for the bill. About one-third favored his vote.

He doesn't come up for election again until 2012, so he'll have plenty of time to craft his retirement speech.
