Early Voting Begins May 18 in San Antonio for Texas Runoffs

Early voting for the May 26 Texas primary runoffs opens today, May 18, across Bexar County with about 50 locations ready for voters. The five-day window runs through Friday, May 22, and gives residents in San Antonio and surrounding areas a chance to cast ballots before the final election date. Turnout in these runoffs will shape the Republican U.S. Senate nomination and several other statewide and local contests.

Locations and Hours in Bexar County

Bexar County has set up roughly 50 early voting sites that include the Elections Office at 1103 S Frio St plus libraries and community centers. Voters may cast a ballot at any of these county locations regardless of their home precinct. Hours run from 7 a.m. to 7 p.m. each weekday during the May 18 through May 22 period.

This setup removes the need for voters to travel to a single central site. County officials have confirmed that every early voting location operates under the same schedule, which matches the statewide runoff calendar set by the Texas Secretary of State.

Key Contests on the Runoff Ballot

The Republican U.S. Senate nomination pits Sen. John Cornyn against Attorney General Ken Paxton. Both candidates advanced from the March primary and now compete for the nomination that determines the party's general election nominee. The outcome will decide which Republican faces the Democratic nominee in November.

Additional statewide and local races also appear on the runoff ballot. These contests cover positions that affect state policy and local governance in Bexar County and across Texas. Voters who participate in early voting can help determine the final nominees in each race.

Deadlines Already Passed for This Election

The last day to register to vote for the runoff was April 27. The final date to apply for a mail ballot that would be received by election officials was May 15. Anyone who missed those cutoffs must vote in person during early voting or on election day.

These deadlines mean most participants will use the early voting period or show up on May 26. County data from previous cycles shows that early voting often accounts for a large share of total turnout in runoffs, especially when high-profile races like the Senate contest draw attention.

Next Steps After Early Voting Closes

Early voting ends at 7 p.m. on Friday, May 22. Election day voting then occurs on Tuesday, May 26, at regular polling places. Results for the statewide races, including the Senate nomination, will be reported after polls close that evening.

Officials will begin counting early ballots once polls open on election day. The final tallies will determine the nominees who advance to the November general election.
