SACRAMENTO, Calif. – California Republicans have initiated a federal lawsuit to block a new U.S. House map that was decisively approved by voters through Proposition 50. The proposition, which aims to assist Democrats in flipping additional congressional seats in the midterm elections, has faced legal challenges questioning its legitimacy.

The lawsuit, filed in the U.S. District Court for the Central District of California, alleges that the map unfairly used racial factors to favor Hispanic voters. Mike Columbo, an attorney representing the plaintiffs, claimed at a news conference that, The map is designed to favor one race of California voters over others, asserting violations of the 14th and 15th Amendments concerning equal protection and voting rights.

This challenge comes as Governor Gavin Newsom and Democrats seek to secure an advantage ahead of the 2026 elections. Newsom's office expressed confidence that the lawsuit would not succeed. The Dhillon Law Group, which filed the suit, is led by Harmeet Dhillon, now serving as an assistant attorney general for civil rights at the U.S. Department of Justice.

As the legal proceedings unfold, it remains uncertain whether a three-judge panel will grant a temporary restraining order before the crucial deadline of December 19, when candidates can begin gathering signatures for reduced filing fees, marking the commencement of their candidacies for the upcoming elections.

Historically, Republicans have encountered multiple legal setbacks in their efforts to contest Democratic initiatives in California. Observers are keenly watching how this latest lawsuit will impact the political landscape as the nation approaches the midterm elections.

In a jab at their opponents, a social media post linked to the lawsuit concluded with, Good luck, losers. With the stakes high for both parties, the battle over California’s congressional map is far from over.
