A new poll shows Sen. Blanche Lincoln (D-Ark.) might be in more trouble than previously thought.

The Talk Business Quarterly poll, which was conducted by The Markham Group (D), The Political Firm (R), and TBQ Editor-in-Chief Roby Brock, shows Lincoln with a 38 percent job approval rating and 56 percent disapproval.

Her favorability is even worse, at just 34 percent, compared to 57 percent unfavorable.

Her favorability and approvals are down eight and seven points, respectively, from the same poll just three months ago, while her unfavorables and her disapproval each rose by 11. That’s a net loss of nearly 20 points on each rating, and the rising negatives are particularly notable.

Both appear to be an indication that health care is hurting her much like is has dented Sen. Ben Nelson’s (D-Neb.) polling numbers.

President Obama’s approval in the poll is 37 percent, versus 61 percent disapproval.
