Here’s what you need to know, per VoteTexas.org:
Register in person at your county Voter Registrar’s office. (In most Texas counties, the Tax Assessor-Collector is also the Voter Registrar. In some counties, the County Clerk or Elections Administrator registers voters.)
Or you can register by mail by obtaining an application from your county Voter Registrar’s office or the Secretary of State’s office. You can also pick up applications at libraries, government offices, or high schools.
After you check, double check and triple check, check out the League of Women Voters of Texas voters guide to learn more about the candidates.
Early voting for the primary begins Feb. 16.
