Louisiana Governor John Bel Edwards speaks to the St. Tammany West Chamber of Commerce about the 2018 legislative budget at The Greystone in Mandeville, La. Tuesday, Feb. 20, 2018.

A new independent poll out shows a solid majority of state voters view Gov. John Bel Edwards favorably, two years into his first term in office.

But the poll also shows that Edwards could face a tough re-election battle if a high-profile, popular Republican makes a bid to unseat him.

Jacksonville, Florida-based Mason-Dixon Polling & Research, Inc. conducted the poll Feb. 20-22. It is based on telephone surveys with 625 registered Louisiana voters and weighted for voter registration by parish. The margin of error is 4 percentage points.

Mason-Dixon paid for the governor-related findings released to the media. The questions for those areas were added to a larger poll that the firm conducted for several public policy groups.

Fifty-five percent of the voters surveyed approve of Edwards' performance, while 31 percent disapprove and 14 percent were undecided.

Edwards polled most popularly among Democrats, the New Orleans and Baton Rouge regions, women, black voters and people younger than 50.

The poll tested Edwards in hypothetical match-ups against Republicans in Congress whose names have been floated as possible challengers. None of the three has entirely ruled out a run, but none has officially launched a campaign.

When paired up against U.S. Sen. John Kennedy, a former state treasurer from Madisonville who was first elected to the Senate in 2016, Edwards had the backing of a nominal 45 percent of respondents to Kennedy's 44 percent.

Kennedy, the newest member of the state's delegation in Washington, has said he's thinking about running.

He fended off 14 candidates to win the open Senate seat, after spending nearly two decades as State Treasurer.

Against U.S. House Majority Whip Steve Scalise, the longest-serving current member of the state's congressional delegation, Edwards had a 46 percent to 43 percent advantage.

Scalise, a former state lawmaker, was near-fatally wounded in a mass shooting during a congressional baseball practice last summer. He's been a close ally of President Donald Trump, even receiving a shout out and standing ovation during Trump's first State of the Union address in January.

The Republican who has shown the most direct interest in challenging Edwards to date, U.S. Rep. Ralph Abraham, who represents northeast Louisiana, struggled the most when pitted against Edwards. The poll showed Edwards with a comfortable 51 percent to 28 percent lead over the two-term congressman, with 21 percent of respondents undecided.
