A new independent poll out in the Louisiana governor’s race shows Democrat John Bel Edwards with a strong lead over Republican David Vitter with less than three weeks until election day.

The poll, conducted by JMC Analytics and Polling for Nexstar TV stations, including WVLA-TV out of Baton Rouge, puts Edwards at 52 percent in the Nov. 21 runoff, to Vitter’s 32 percent. Sixteen percent of those surveyed said they remain undecided.

Edwards, a state representative from Amite, and Vitter, a U.S. Senator from Metairie, came in first and second place, respectively, in Louisiana’s Oct. 24 primary. Because neither got more than 50 percent of the vote, the runoff will decide Gov. Bobby Jindal’s successor.

The poll found Edwards pulling in 41 percent of the white voters surveyed and 24 percent of Republicans.

JMC surveyed 600 likely voters Oct. 28-31. The margin of error is 4 percent.

The poll lines up with internal polling in the days after the primary and a recent poll commissioned by the anti-Vitter GumboPAC. That poll, conducted by Anzalone Liszt Grove Research, had Edwards leading Vitter 52 percent to 40 percent, with 7 percent undecided.
