Democratic Rep. Doris Matsui won reelection to a U.S. House seat representing California on Tuesday. She was elected to succeed her late husband in 2005 after he died in office. Matsui has secured reelection comfortably in every race since. She easily defended her seat in the primary against a Democratic challenger, David Mandel, who ran on a platform of Palestinian human rights and demanding a cease-fire by Israel in Gaza. The 7th District, which includes most of the state capital of Sacramento, has been solidly Democratic since 1958. declared Matsui the winner at 11:27 p.m. EST.
