Redistricting Fight Puts House Seats in Play
A mid-decade redistricting campaign launched by Republicans in 2025 is now being tested in the midterm elections. Republicans are seeking to flip 15 seats across seven states with new maps; Democrats have six potential pickups in California and Utah, where a court ordered a new map. With control of the House at stake, these contests could shape which party holds the chamber in January.
In Texas, Republicans redrew congressional districts with the aim of flipping five Democratic-held seats. The new map targets three seats in southern Texas and one each in the Dallas and Houston areas. Political science professor Mark Jones of Rice University said Republicans could struggle to reach five gains, and that getting beyond three looks difficult. He also said the changes could put a Republican-held seat at risk in a district extending from San Antonio to the border.
California’s Proposition 50 redrew five districts to favor Democrats, after Texas Republicans changed their map. Democrats are expected to gain at least three seats, while two other newly drawn districts are more competitive. Among the closely watched contests are races in the Central Valley and San Diego and Riverside counties. Several districts also feature Democratic challengers running against Democratic incumbents, including contests in San Francisco, Sacramento and Los Angeles.
New maps can reshape which voters are grouped together, and the party seeking gains may also weaken its position elsewhere in a state. The outcome depends on the overall seat balance, not just victories in targeted districts. In California, counties may continue counting ballots received for up to seven days after Election Day.
GOP’s Redistricting Push Faces a Test at the Ballot Box
Republicans launched a mid-decade redistricting drive in 2025 to protect their narrow House majority, and the strategy now faces voters. The party is targeting 15 seats across seven states with new maps. Democrats have six potential pickups in California and Utah, illustrating how map changes have turned the battle for the House into a contest over districts reshaped by partisan actors.
Texas shows the limits of the GOP’s ambitions. Republicans redrew the state map hoping to flip five Democratic-held seats, including districts in southern Texas, Dallas and Houston. Rice University political science professor Mark Jones said the party is unlikely to reach five and may struggle to get much beyond three. He also warned that a heavily altered district extending from San Antonio to the border could cost Republicans a seat of their own.
California voters approved Proposition 50, redrawing five districts to favor Democrats after the Texas changes. Democrats are expected to flip at least three Republican-held seats, while the Central Valley and San Diego-Riverside districts remain more competitive. Those races, alongside contests featuring progressive Democrats challenging party incumbents, could shape both House control and the party’s direction.
The stakes go beyond the races each party deliberately targeted: a map can concentrate or spread voters in ways that hurt its authors elsewhere. Republicans’ effort to engineer gains could therefore fail to deliver a net benefit. California counties may count ballots received for as long as seven days after Election Day.
Democratic Counter-Maps Put House Seats in Play
Democrats are using newly drawn districts to pursue House gains after Republicans changed maps in Texas and other states. California’s Proposition 50 redrew five districts to favor Democrats, and a court-ordered map in Utah has added another opening. The races could help decide control of Congress, but the overall outcome depends on net gains, not just victories in districts each party targeted.
Texas Republicans set out to flip five Democratic-held seats with a new map. Rice University political science professor Mark Jones said that goal is likely to fall short, with gains beyond three looking difficult. The redistricting may also endanger a Republican incumbent in a district extending from San Antonio to the border. A map designed to produce gains can carry risks for the party that draws it.
In California, Democrats are expected to win at least three seats now held by Republicans, while two newly drawn districts are more competitive. The Central Valley contest pits Republican incumbent David Valadao against Democrat Randy Villegas; in the San Diego and Riverside area, Democrat Marni von Wilpert faces Republican Jim Desmond. Other closely watched races pit Democrats against fellow Democrats, including progressive challengers seeking to shift the party’s direction.
The maps have made partisan line-drawing central to the fight for the House. Republicans’ Texas plan and Democrats’ California response both reshape which voters are grouped into districts, while results across each state will determine whether the changes produce a net gain. California counties may continue counting ballots received for up to seven days after Election Day.
