Trump-endorsed Louisiana Attorney General Jeff Landry will be the first Republican in eight years to move into the governor’s mansion after a dominant walk-off primary win on Oct. 14.
With 95 percent of the tally counted, Mr. Landry won 51.6 percent of more than 1 million ballots cast in the off-year election, more than doubling the combined votes of 13 other candidates—including six fellow Republicans—making a Nov. 18 runoff unnecessary.
