The 2019 Louisiana gubernatorial election will be decided by a runoff election on November 16 after none of the candidates achieved more than 50% of the vote in the state's gubernatorial primary.

Democratic incumbent John Bel Edwards won a plurality with 46.6% of the vote in October 12's primary, but it was not enough to secure him outright victory. Edwards will face Republican businessman Eddie Rispone, who received 27.4% of the vote, in November's runoff.

Despite Edwards' plurality, President Donald Trump tweeted a congratulations to both the state of Louisiana and Rispone.

"Congratulations to the Great State of Louisiana. A big night. You will soon have a new and wonderful Governor, Eddie Rispone," the president said.

Louisiana operates a jungle primary system for its gubernatorial elections. Under a jungle primary, all candidates, even ones from the same party, appear on the ballot together. If one candidate receives more than 50% of the vote, that candidates wins the election outright. If no candidate receives more than 50%, the top two candidates participate in a runoff election to determine who will become governor.
