The poll also found a tight race between Cotton and Pryor which may be good news for Pryor, who is considered one of the most vulnerable Democrats in the country. The poll found Cotton and Pryor tied with 39 percent each. Twenty-two percent said they weren't sure.

It's the latest bit of good news for Pryor. A string of recent polls -- many of them commissioned by Democratic groups -- have found Pryor actually leading Cotton in the Arkansas Senate race.

The poll was conducted from April 9 to April 10. Harper polling surveyed 522 likely voters and had a margin of error of plus or minus 4.29 percentage points.
