The Louisiana presidential preference primary for Republicans and Democrats is March 5, but early voting starts Saturday and runs through Feb. 27.

Voters can cast early ballots daily from 8:30 a.m. to 6 p.m., except for Sunday.

Only voters who are registered to one of the two political parties will be able to vote for their party’s nominee, because, unlike most elections in Louisiana, the presidential primary is a closed primary.

The Democratic Party and the GOP will also have closed state central committee and parish executive committee elections.

Those who aren’t party affiliated may still have local elections to vote in.

According to the Secretary of State’s Office, parishes with open local races include: Acadia, Beauregard, Caddo, Caldwell, Catahoula, Concordia, East Baton Rouge, East Feliciana, Evangeline, Iberville, Jackson, Jefferson, Lafourche, Livingston, Morehouse, Natchitoches, Ouachita, Red River, St. Helena, St. Landry, St. Martin, St. Tammany, Tangipahoa and West Baton Rouge.

“This is an election where voters should absolutely check to see what’s on their ballot before they go vote,” Secretary of State Tom Schedler said in statement. “Louisiana has a large number of unaffiliated or no party voters who aren’t eligible to participate in the (presidential primary), but should vote in any local elections for their area. Early voting is a convenient way to get your ballot cast ahead of time and is typically quick and easy.”
