Republican Rob McKenna and Democrat Jay Inslee are looking ahead to the November election in their race for Washington governor. But the final candidates for several other state races will be determined by the results of Tuesday's top-two primary.

The primary also will pick the candidates racing to fill the congressional seat Inslee gave up to run for governor. There's an open race to replace retiring Congressman Norm Dicks, and the first contest in the new 10th District.

The primary also may determine if former state Supreme Court Justice Richard Sanders will regain the seat he lost two years ago. Justices Susan Owens and Steve Gonzalez are running to retain their seats. If someone wins more than 50 percent of the vote, they will advance alone.
