The Issues

For the past several weeks, Texas Scorecard has asked runoff candidates questions on hot-topic issues voters care about as they head to the polls. Notably, Barron Casteel never responded to any of Texas Scorecard’s inquiries.

On the issue of ending Democrat committee chairs in the Republican-majority Texas House, Isaac supports ending the practice.

Regarding extending the protections for girls’ sports to women’s collegiate athletics to prevent men pretending to be women from competing in women’s athletics, Isaac supports the protections.

Isaac supports property tax relief, with plans to use excess state revenue to buy down school maintenance and operation taxes, which are the largest portion of the property tax bill on every homeowner’s kitchen table.

Protecting parental rights in education by preventing kindergarten through third-grade students from being taught harmful gender ideologies is an issue Isaac supports.

The border crisis is an invasion, and Isaac supports Texas’ work to secure the border despite pressure from the left.

Closing the loopholes in Texas obscenity laws that allow for pornographic books in children’s schools is something Isaac is in favor of accomplishing.

Isaac supports ending corporate welfare in Texas, stating, “Not only have handouts brought woke companies to Texas, but the property tax exemptions and credits for wind and solar have eroded our electric reliability while increasing costs.”

Regarding vaccine mandates, Isaac opposes them, having signed the Texans for Vaccine Pledge to prohibit vaccine mandates in Texas.
