A new poll from Talk Business found Mark Pryor, the sitting Democratic senator from Arkansas, with a three-point lead over Republican challenger Tom Cotton. The survey of more than 1,000 likely voters found 45.5 percent said they would vote for Pryor, while 42.5 percent said they would vote for Cotton.
The poll also found that Pryor has a 10-point lead among women, while Cotton has a 7-point lead among men and just a 5-point lead among white voters.
The poll is the first since October to show Pryor ahead. The Real Clear Politics poll average shows Cotton with a slight lead of 1.5 percentage points.
Pryor, who was first elected to the Senate in 2002 and was reelected in 2008, voted to pass Obamacare in 2010. He has said he still would have voted for it, knowing what he knows now about the law's problems.
