According to unofficial totals from the Harris County Clerk's Office, about 212,000 votes were cast during early voting, including 204,993 in-person votes and 7,111 mail-in ballots. That means almost 8% of the county's 2.7 million registered voters participated early.

That’s nearly 607,000 less votes compared to the 2024 general election early voting numbers, where Harris County voters cast more than 686,500 ballot votes. The county’s voter registration department found that more than 2.5 million people are registered voters in the county.

For the 212,000-plus voters who cast ballots during the early voting period, the Cy-Fair ISD school board race and a special election in Texas' 18th Congressional District appear to have been the most significant drivers for turnout.
