Texas Sen. John Whitmire is projected to be Houston’s next mayor after beating his opponent, U.S. Rep. Sheila Jackson Lee, in a special runoff election on Saturday.

Whitmire inherits a city facing many challenges, including crime, crumbling infrastructure, and potential budget shortfalls. But despite these issues, booming growth over the last decade has turned the nation’s fourth-largest city into an expanding stronghold for Texas Democrats.

Jackson Lee and Whitmire, both Democrats, made it to Saturday’s runoff after breezing past a crowded field of nearly 20 candidates in the Nov. 7 general election.

Jackson Lee, 73, has represented Houston in Congress since 1995. Before that, she served on Houston’s City Council.
