Rep. Tom Cotton (R-AR) gained a lead over incumbent Sen. Mark Pryor (D-AR) with likely voters in the Arkansas senate race in a new NBC/Marist poll released Sunday.
Among likely voters, 45 percent said they would support Cotton and 40 percent said they would support Pryor. But with registered voters, the candidates were tied 41-41 for voters’ support.
In NBC/Marrist’s May poll, Pryor had an 11-point lead among registered voters, which may show that Pryor is slipping overall.
Before the latest NBC poll, TPM PollTracker’s average had Pryor leading Cotton by one point.
NBC/Marist surveyed 691 likely voters with a margin of error plus or minus 3.9 percentage points and 1,068 registered voters with a margin of error plus or minus 3 percentage points. The poll was conducted via phone Sept. 2-4.
