In a new survey by North Carolina-based Public Policy Polling, Senator David Vitter leads the pack in run-off matches against three potential opponents in the 2015 race for governor.

Pollster Tom Jensen says Vitter has strong approval ratings, which will make him tough to beat.

"48 percent of the voters approve of him, 35 percent disapprove," Jensen said. "When you compare that with Bobby Jindal and Mary Landrieu it makes Vitter the most popular politician in the state."

In the survey of 664 registered voters, Vitter  defeated democratic state representative John Bel Edwards in a possible run-off, and also came out on top against Lt. Governor Jay Dardenne and New Orleans Mayor Mitch Landrieu.

Jensen says in a speculative run-off with Landrieu, Vitter received 48-percent and the mayor got 44-percent.

"He has the popularity and it looks like he could make it a race, if he decides to get in," he added. "It's just a question of whether he ends up doing that."
