In the 7th District, Democrat Doris Matsui won reelection to the U.S. House of Representatives, defeating fellow Democrat Mai Vang. Matsui, 82, has represented the Sacramento area since 2005, when she won a special election to succeed her late husband, Robert Matsui. Her campaign emphasized her experience and record of securing federal funding. Vang, 41, campaigned on the need for generational change within the Democratic Party. The district, which includes Sacramento, Elk Grove, and parts of the Sierra foothills, underwent redistricting that added more conservative voters to the area. ## Timeline ### 2026-11-09: Doris Matsui wins reelection to California's 7th Congressional District Democrat Doris Matsui has defeated challenger Mai Vang to retain her seat in California's 7th Congressional District. 4 sources. https://clstr.news/cluster/doris-matsui-wins-reelection-to-us-house-in-california ### 2026-11-03: California Democrats win key Congressional seats Democrats won key California congressional races, with Marni von Wilpert taking the 48th District and Randy Villegas unseating Republican incumbent David Valadao in the 22nd District. 9 sources. https://clstr.news/cluster/richard-pan-wins-election-for-californias-6th-congressional-district --- Cite as: California midterm election results.
