California Gov. Jerry Brown (D) has set the date for the special election to fill former Rep. Jane Harman's (D) seat.

The vote will take place on July 12, with the primary set for May 17, according to the Sacramento Bee. The nomination contest will be the first congressional primary to employ the state's new top-two system, wherein the two candidates who receive the most votes advance to the general. The general election could be two Democrats, in this case.

The competition on the Democratic side is between Los Angeles City Councilwoman Janice Hahn and Secretary of State Debra Bowen. Two Republicans, Redondo Beach Mayor Mike Gin and Redondo Beach City Attorney Mike Webb, are also vying for the seat.

Democrats are heavily favored to retain the 36th district in the special election.

Harman left Congress on Feb. 28 to join the Woodrow Wilson International Center for Scholars.
