LOS ANGELES (FDN) — In a critical lead-up to Election Day, California's contentious new U.S. House district maps are fueling intense political battles, with the potential to eliminate several Republican seats. Just days before voters cast their ballots, the momentum appears lopsided as opponents struggle with dwindling campaign resources.

While the dynamics could shift before the polls close on November 4, data reveals a dramatic drop in advertising from Republican critics, overshadowed by a nearly $9 million advertising campaign by Democratic supporters. This campaign, led by Governor Gavin Newsom, seeks to bolster his party's chances of reclaiming a House majority in the 2026 elections, countering Republican strategies focused on strengthening their representation in states like Texas.

According to AdImpact reports, Democratic advocates have executed nearly $70 million in advertising whereas their opponents have only managed about $31 million. Over 1.5 million mail-in ballots have been returned by Democrats compared to approximately 853,000 from Republicans—the disparity is consistent with California's two-to-one Democratic advantage among registered voters.

The stakes are high; should Democrats succeed in passing these new maps, they could command up to 48 of California’s 52 congressional seats. Newsom emphasized the importance of this election in fundraising appeals, warning that a loss could signify a near-impossibility for Democrats to reclaim the House. Moreover, failure here could severely impede not just Democratic influence in California but also threaten broader national efforts to counter GOP dominance.

Critics, including deep-pocketed Republican donors, view the redistricting move by Newsom not just as a strategy against Trump but as a blatant power grab that undermines independent redistricting efforts established in the past. This brewing fight hints at a pivotal moment in determining the balance of power within Congress, influencing both local voters and the national political landscape as the midterms draw near.
