But a nonpartisan poll released shortly after Pryor's from Talk Business and Hendrix College found Cotton leading Pryor by 44 percent to 42 percent. The automated poll with a live-caller cell phone sample is considered one of the better surveys in the state.
Partisan polling should always be taken with a grain of salt, and Arkansas may be the state where Democratic and Republican polling have differed the most this election cycle. Cotton released his own poll in mid-June that found him leading Pryor by 47 percent to 40 percent.
There has been little public polling of the race from nonpartisan live-calling pollsters, but most of what has been out there has found a tight race.
"The election is far from over, but Mark Pryor has to be considered the favorite to win in Arkansas," argues an accompanying polling memo from Pryor pollster Andrew Maxfield.
Pryor's poll also found a close gubernatorial race, with former Rep. Asa Hutchinson (R-Ark.) leading former Rep. Mike Ross (D-Ark.) by 42 percent to 41 percent.
The liver-caller landline and cell phone poll of 807 likely voters was conducted by telephone from July 7-10, 2014 and has a margin of error of plus or minus 3.5 percentage points.
