Redistricting under Proposition 50 shifted California's 22nd District boundaries to include more Democratic-leaning areas in Fresno and Madera counties while removing some Republican strongholds, creating a narrower path for incumbent David Valadao. Valadao's vote for Medicaid reductions stands out in a district where roughly 60 percent of residents rely on Medi-Cal, amplifying Democratic messaging on healthcare access ahead of the November 3 general election. Randy Villegas, the Democratic nominee and a progressive backed by organized labor and national party resources, has benefited from these dynamics plus heavy outside spending on both sides. Trader consensus reflected in the 90 percent probability for Villegas incorporates polling leads for the challenger, Valadao's history of outperforming the top of the ticket, and the competitive environment for House control.
