Sen. David Vitter (R-LA) trails Democratic gubernatorial rival John Bel Edwards by 12 points after edging out his Republican challengers in Saturday’s jungle primary, according to a Democratic poll made public Thursday.

The survey conducted by Democratic polling firm Anzalone Liszt Grove on behalf of the anti-Vitter Gumbo PAC found Edwards, a state representative, leading the senator 52 percent to 40 percent. The runoff is Nov. 21.

Notably, the poll found that voters who cast their ballots for losing Republican candidates Scott Angelle and Lt. Gov Jay Dardenne are now just as likely to choose Edwards as they are to choose Vitter. Forty-seven percent of those Republican voters said they’d be likely to move toward Edwards while 46 percent said they’d be likely to move toward Vitter.

Those Republican voters also have a more favorable view of Edwards than they do of Vitter. Forty-seven percent of Angelle and Dardenne supporters said they viewed Edwards favorably compared to forty percent who said they viewed Vitter favorably.

The poll surveyed 700 likely runoff voters by phone from Oct. 26-28. The survey had a margin of error of 3.7 percentage points.

Correction: This post has been updated to reflect that Edwards leads Vitter 52-40, not 50-42.
