First up is the 7th Congressional District, an area west of Houston proper. The race has been recently consumed by tumult after the Democratic National Campaign Committee raised concern about the viability of Democratic candidate Laura Moser. Moser is one of seven Democrats running against incumbent Republican Rep. John Culberson (R-TX). While the district narrowly backed Clinton in the 2016 presidential election, it has not elected a Democrat to the House since 1967. Among other candidates competing for the Democratic nomination, Jason Westin, a doctor, Lizzie Pannill Fletcher, a Houston attorney, Moser and Alex Triantaphyllis, a nonprofit executive, are viewed as the likely top-tier candidates.

In Texas’ 32nd Congressional District, which is in the Dallas area, there is an equally packed Democratic primary. The winner will face off against incumbent Republican Rep. Pete Sessions (R-TX) who has represented the district since 2002.
