Ben Nelson below 50 percent in his home state."](CNN) - Sen. Ben Nelson's support in his home state of Nebraska has dipped below 50 percent, according to a new poll which finds a majority of voters there disapprove of the Democratic health care bill the two-term senator supports.
According to a new poll conducted by the Omaha World-Herald, Nelson's job approval rating now stands at 42 percent with a 48 percent disapproval rating. Forty-four percent of those polled also said Nelson's support for the health care reform bill would hurt his chances at re-election 2012 should he decide to run.
Nelson was the last Senate Democrat to sign on to his party's health care bill, and has since been criticized for only agreeing to the bill after winning special concessions from Senate Majority Leader Harry Reid.
The poll found that more than 60 percent of Nebraskans questioned oppose the Senate health care bill.
A majority said they opposed Nelson's vote in favor of the bill, while about 1 in 3 approved of it. Three-quarters of the GOP voters surveyed - but only 22 percent of Democrats - opposed the senator's vote.
Nelson, who served as governor of Nebraska from 1991-1999, has long been a popular figure in the state. He was re-elected in 2006 to his second Senate term with 64 percent of the vote.
The same poll out Monday shows fellow Nebraska Sen. Mike Johanns, a Republican who voted against the health care measure, with a 63 percent approval rating.
The poll surveyed 500 registered voters in Nebraska between Jan. 8-12. It has a sampling error of plus or minus 4.4 percentage points.
