This much is clear — the congressman for the 15th District will be a Democrat.
Rep. Pete Stark and Dublin city councilman Eric Swalwell finished first and second in the primary election Tuesday. Conservative Chris Pareja finished a distant third.
With 100 percent of the precincts reporting, Stark won 42.9 percent of the vote. Swalwell finished with 35.3 percent and Chris Pareja received 21.5 percent of the vote.
That means Stark and Swalwell will compete head-to-head for the open seat, which represents San Ramon, Dublin, Pleasanton, Livermore, Castro Valley and Union City.
Patch will have a full story on election night later on Wednesday.
