Two San Antonio-area incumbents battling to keep seats in Tuesday's runoff

A pair of San Antonio-area incumbents — one Republican and one Democrat — face high-stakes races in Tuesday's runoff elections. Republican two-term incumbent U.S. Rep. Tony Gonzales is defending his seat representing the 23rd District, which includes West San Antonio and a large chunk of South Texas after failing to land 50% of the vote in a five-way primary. He's locked in a runoff with pro-gun rights YouTube personality  Brandon Herrera, a political novice.
