Barack Obama has stepped into the high-stakes battle for control of the U.S. House of Representatives, appearing in a new 30-second campaign ad urging Californians to support Proposition 50, a November ballot measure that could dramatically reshape the state’s congressional map.
The initiative aims to create as many as five new Democratic-held House seats in California, which could be decisive in the struggle for control of Congress. Proposition 50 was drafted by Democratic strategists to secure House gains and offset President Donald Trump’s efforts in Texas and other Republican strongholds to expand the GOP’s majority in the 2026 midterm elections.
“Republicans want to steal enough seats in Congress to rig the next election and wield unchecked power for two more years,” Obama says in the ad, speaking directly to viewers. “You can stop Republicans in their tracks.”
Democratic Gov. Gavin Newsom has characterized the California redistricting measure as a referendum on Trump’s influence, arguing that Democrats must counter Republican moves to tilt the balance of power. Voting on the proposal began earlier this month and concludes Nov. 4.
Republican leaders and opponents of Proposition 50 have condemned it as a blatant power grab. They argue that the measure would override district boundaries set by California’s independent redistricting commission, which was established by voters more than a decade ago to remove partisan influence from the process.
The political fight mirrors a growing national showdown between California and Texas, the nation’s two most populous states. In North Carolina, Republican legislative leaders announced plans this week to vote on new congressional maps, echoing Trump’s call to lock in additional GOP seats nationwide as Democrats push to redraw maps in their favor elsewhere.
Currently, Republicans hold a narrow 219–213 majority in the House, with three vacant seats. If California voters approve Proposition 50, the new map could cut five Republican-held districts while shoring up Democratic incumbents in battleground areas. That would give Democrats as many as 48 of California’s 52 House seats, up from 43 today — a shift that could be pivotal in deciding House control.
