The Arkansas Senate race has narrowed, according to a new poll which shows Democratic Sen. Mark Pryor leading Republican Tom Cotton by 2 points.

The Suffolk/USA Today survey released Wednesday found Pryor leading 45 percent to 43 percent, within the poll’s margin of error. Seven percent were undecided.

Remarkably, the one-fifth of Arkansas voters who name health care as their top priority support Pryor by a margin of 50 to 39 percent, the poll found. The statistic cuts against predictions that Obamacare would damage Democrats in the midterm elections.

The result is welcome news for Pryor as Cotton has led in polls conducted over the last month by NBC/Marist, CNN, CBS/New York Times and the Democratic-affiliated Public Policy Polling.

Cotton leads Pryor by 1.4 percentage points, according to the TPM PollTracker average.
