The first day of early voting for the May 22 primary runoff elections is Monday. Residents have a chance to vote in several local, state and congressional races to determine which Democrats or Republicans will be the nominees for their parties. In U.S. House District 21, Democratic candidates Mary Street Wilson and Joseph Kopser will face off. On the GOP side, Chip Roy and Matt McCall head to a runoff after making it through the primaries against 16 other candidates. U.S. House District 21, represented by outgoing Republican Lamar Smith, includes Hays County and parts of San Marcos, Buda, Kyle and Austin. In the statewide race for governor, Democratic candidates Lupe Valdez and Andrew White will face off. Whoever wins will run against incumbent Gov. Greg Abbott in November. Residents living within State House District 45—which encompasses Dripping Springs, Wimberley, Kyle and San Marcos—will see two names on the Democratic ballot: Rebecca Bell-Metereau and Erin Zwiener. Locally, Republican candidates John Burns and Rober Avera will face off for the nomination of Hays County Justice of the Peace Precinct 4. Republicans Michael "Mike" Toth and Donna Davidson will be on the runoff ballot for the 3rd Court of Appeal District Place 6 judge nomination. Runoffs occur when no candidate receives at least 50 percent of the vote during the primary elections. If you did not vote in the March 6 primary elections, you can still vote in the May 22 primary runoff elections. If you voted in the March 6 primary elections, you must vote with the same party in the May 22 runoff elections. The last day of early voting is May 18, and Election Day is May 22. Polls are open from 7 a.m.-7 p.m. on Election Day. See what your ballot looks like here.
