BATON ROUGE, La. (AP) — Gov. Bobby Jindal easily coasted to a second term on Saturday, winning in a landslide after failing to attract any well-known or deep-pocketed opposition.

Mr. Jindal, 40, a Republican, overwhelmed nine competitors in the vote, an open primary; a candidate wins the race outright if he or she receives more than 50 percent of the vote. With four-fifths of precincts reporting, Mr. Jindal had received about two-thirds of the total vote.

His closest competitor, Tara Hollis, a Democrat, took about one-fifth of the total. All the others were in single digits.

“I will use every day, every hour of these next four years to make Louisiana the very best that we can be,” Mr. Jindal told a packed hotel ballroom of supporters in Baton Rouge. “I don’t believe in resting on our past accomplishments. I don’t believe in taking time off.”
