Democratic presidential candidate Hillary Clinton will be in North Carolina Thursday to campaign ahead of the March 15 primary and encourage early voting, her campaign announced Saturday.

Details about Clinton’s visit – including where she will campaign in the Tar Heel State – have not been released.

Clinton and Democratic candidate Bernie Sanders will be trying to lock up delegates in three states Saturday – voters head to the polls for primaries in Kansas, Louisiana and Nebraska. The pair will also participate Saturday night in a debate in Flint, Michigan.

Early voting for the March 15 primary started Thursday across North Carolina, and after years of debate and lawsuits, showing photo identification at the polls is now a fact of life for North Carolina voters.

Every voter is being asked for a photo ID, even if they’ve voted at the same precinct for years and the poll workers know them.

Acceptable IDs:

North Carolina driver's license or learner's permit, either current or expired within four years

Veteran's ID card or U.S. military ID

Unexpired U.S. passport

Tribal ID card

State-issued ID

Out-of-state driver's license (only for someone who registered within 90 days of the election)

If a voter forgets to bring an ID, he or she can cast a provisional ballot. For the vote to count, however, the person will need to show his or her ID at the county elections office afterward.
