Republicans are losing support among Latinos. It might cost them the House.

Competitive House districts across key battleground states now feature Latino voters as the dominant or nearly dominant demographic, reshaping the political landscape in regions from the South to the West Coast. This demographic shift reflects broader changes in voter composition and could influence election strategies and campaign priorities in tightly contested races. The growing Latino electorate underscores the importance of language, policy platforms, and outreach efforts tailored to this community. With these districts playing a pivotal role in national elections, the influence of Latino voters may determine outcomes in some of the most closely watched races.

Many of the most competitive House districts this year, in states from Texas to Florida, California to Pennsylvania, have majority or near-majority Latino electorates.
