State Sen. Mark DeSaulnier, D-Concord, came in first and is headed to the November runoff, continuing his march to represent the 11th Congressional District seat held by George Miller, the doyen of California's congressional delegation.

Republican Tue Phan, of Danville, came in a distant second and will face off against DeSaulnier in the November general election. Democrats Cheryl Sudduth of Richmond, Tony Daysog of Alameda and Ki Ingersol of Benicia and independent Jason Ramey of Concord lagged far behind. The 11th District covers most of Contra Costa County, including Richmond, Walnut Creek, Concord, Clayton, Danville, Orinda, Pittsburg, San Pablo, Moraga and Lafayette. Registered Democrats outnumber Republicans about 2 to 1.

DeSaulnier, 62, said he wants to cut off federal funding for a high-speed rail link between the Bay Area and Southern California; Phan, 72, wants it to continue. Both candidates advocate universal background checks for gun owners.

In the hotly contested 17th Congressional District, which includes parts of Alameda and Santa Clara counties, longtime Rep. Mike Honda, 72, of San Jose, finished first over fellow Democrat Ro Khanna, 37, of Fremont, an attorney and former deputy U.S. commerce secretary. Honda led Khanna by about a 2-1 margin late Tuesday, and both are on the way to the "top-two" final in November. Republican rivals Vanila Singh, 43, of Fremont, and Joel VanLandingham, 47, of San Jose, are out.

In the 15th Congressional District, Rep. Eric Swalwell, D-Dublin, will head to the November runoff, as expected. He led almost 2-1 over his challengers, state Senate Majority Leader Ellen Corbett, D-San Leandro and Republican Hugh Bussell, of Livermore, who were in a tight battle for the second spot at press time.

Two years ago, Swalwell was a Dublin councilman and the insurgent David who toppled his own party's veteran Goliath, 20-term incumbent Rep. Pete Stark.
