In the race for Texas House District 45, incumbent Democrat Erin Zwiener raised more cash between July 1 and Dec. 31 of last year, though one of her Republican challengers, Carrie Isaac, has the most cash on hand as of the reporting deadline of Jan. 15. Also in the GOP primary race are Kent “Bud” Wymore and Austin Talley.

Isaac is the wife of former State Rep. Jason Isaac, whose seat Zwiener won after he lost the Republican primary to U.S. Rep. Chip Roy in the District 21 race.
