LOS ANGELES (AP) — As Election Day nears, California's contentious redistricting proposal is shaping up to be a critical flashpoint in the race to control the U.S. House. Advocates argue that this new map, pushed by Democratic Governor Gavin Newsom, could potentially eliminate five Republican-held seats, sparking significant concern for GOP candidates.

Recent reports indicate a dramatic decline in campaign advertising from Republican groups, which raises questions about their ability to mount a viable challenge against the Democratic push. With over $9 million in TV ad spend backing the proposal, Democrats are capitalizing on their funding advantage, while Republican campaign efforts seem stalled.

Since voting commenced earlier this month, Democrats have seen more than 1.5 million mail ballots returned compared to approximately 853,000 from Republicans. This disparity aligns with California's demographic makeup, where registered Democrats significantly outnumber GOP voters.

As the campaign for Proposition 50 unfolds, the political fallout could reach far beyond state lines. Observers note that a Democratic House majority would represent a considerable obstacle for President Trump's agenda, especially as Newsom positions himself as a potential candidate for the 2028 presidential race.

Notably, funding woes have plagued Republican challengers, with hopes for national donor support fading as attention turns to other critical House races across the country. Some strategists worry about the possibility of GOP dollars being redirected, leaving California's conservative voters in a precarious position. Tim Lineberger, a former communications director for Trump's campaign, highlighted the importance of GOP engagement in California, insisting it remains a vital battleground.

Meanwhile, Charles Munger Jr., a key financier of the campaign against the redistricting, warns that Newsom's plan could distort voter representation for political gain.

As Election Day approaches, Republicans are strategizing to increase turnout among their base while courting independents and disaffected Democrats. The outcome of this fight may determine not only the political landscape of California but also the trajectory of national politics in the lead-up to the 2026 midterm elections.
