Whitmire went up against Molly Cook, an emergency room nurse and community advocate, who finished with 42.5% of the vote, or 18,260 votes.

In a Q&A with Community Impact Newspaper, Whitmire said he thought the most pressing issues facing District 15 related to public safety, health care and flooding. Among his priorities for the 2023 legislative session are enacting bail reform, pushing for the expansion of Medicaid in the state, and fighting for more flood control resources to go toward drainage and building another reservoir.

Whitmire has served in the Texas Senate since 1983 and currently as the chair of the Senate Criminal Justice Committee.

In a statement on Twitter, Whitmire thanks his voters for their support.

"I ran on my record, [and] you rewarded me with your vote," he said. "I will continue to be a fighter for you in Austin [and] use my experience to make the district a better place to work and live."
