Several key Republican seats in Dallas County were lost last night to Democratic challengers.

Most notably, Rep. Pete Sessions, R-Dallas, a 15-year veteran of the U.S. House, must now pass the baton to underdog Colin Allred, his Democratic challenger

Don Huffines, R-Dallas, who has held control over a historically red district in the state Senate since 2015, lost his seat to Nathan Johnson, a Democrat. Incumbent state Rep. Linda Koop, R-Dallas, whose district covers North Dallas, Richardson and Addison, will also vacate her seat to Democratic challenger Ana-Maria Ramos.

Still, several Republican incumbents in the Dallas County judicial system and law enforcement will continue for another term. Those positions include Al Cercone and Steve Seider—justices of the peace in Precinct 3—and County Constable Ben Adamcik.

In stark contrast with Dallas County was the Collin County portion of Richardson, where several newcomer Republicans took hold of notoriously red districts.

Republican Angela Paxton, the wife of state Attorney General Ken Paxton, took the District 8 state Senate seat left behind by Van Taylor, R-Plano. Paxton emerged with a narrow victory over Democratic challenger Mark Phariss, who sought to become Texas' first openly gay senator.

Paxton's predecessor, Taylor, won his U.S. congressional bid for District 3, which covers a large portion of Collin County. The seat was recently vacated by nearly 30-year Republican veteran Rep. Sam Johnson.

Narrowly edging out a win was incumbent state Rep. Matt Shaheen, R-Plano, who beat his Democratic challenger Sharon Hirsch by less than a full point. Rep. Jeff Leach, also an incumbent Republican from Plano, emerged victorious over his opponent Sarah Depew.
