Tom CottonThomas (Tom) Bryant CottonSenate confirms Haspel to head CIA Democrats urge colleagues to oppose prison reform bill Trump-backed prison reformsĀ face major obstacles in Senate MORE (R-Ark.) in a new poll released by the Democratic Senatorial Campaign Committee.

Pryor leads Cotton by 48 percent to 45 percent in the poll.

The numbers are the latest sign that Pryor hasn't withered under a deluge of attacks in the conservative state, and that the race is likely to remain tight.

Partisan polls should always be taken with a grain of salt. But Pryor has led in two other recent polls: A Talk Business-Hendrix College poll out last week found him with the same 3-percentage-point lead, and one from Opinion Research Associates found him leading by 10 points.

The live-caller poll of 600 likely voters was conducted by the Democratic firm Anzalone Liszt Grove Research from March 27 through April 2. It has a margin of error of plus or minus 4 percentage points.
