Key political primaries will be decided Tuesday as voters head to the polls once again.

The ballots started being cast at 7 a.m. for the runoffs, and the polls will remain open until 7 p.m.

According to the Brazos County clerk's office, turnout was a bit slow to start the day, but officials also want to emphasize that you can still vote in a runoff even if you didn't vote in a March primary.

There was an issue at Aldersgate Methodist Church in College Station Tuesday morning, which acts as Precinct 40. According to county officials, six voters were mistakenly turned away by election workers because they had not voted in the primary. If you were one of those voters, you're asked to head back there and vote.

- The District 14 seat in the Texas House of Representatives will also be decided. Incumbent Fred Brown and Buddy Winn are in a runoff to determine the Republican nominee, but with no other candidates running for the office, one of these two men will be sent by the voters to Austin.
