California election results: Latest on governor, House, LA mayor primaries

Residents across California have decided on candidates for dozens of November midterm elections, including closely watched races for governor and Los Angeles mayor.

Voters also chose Republican and Democratic candidates in each of the Golden State's 52 congressional districts to vie for seats in Washington this fall.

The packed roster of California House races could hold the key to a House majority. As the state with the most seats in the U.S. House of Representatives, the results of the November midterms could impact Republicans' narrow majority in the chamber and come amid redistricting efforts in the state to secure Democratic wins.

"The Golden State will provide a good idea of whether the Democratic response to the Texas gerrymander is likely to succeed," says John McGlennon, professor of government at the College of William & Mary. "Contests all over the state will set up the top-two races in the fall, and this vote will show if the Democrats do in fact wind up having the edge in five more districts than they hold today."

Importantly, California's open primary system means the top two candidates in each race advance to the general election, regardless of their party. This means candidates can vie against their own party not just in the primary, but in the general election as well.

Here are some of the results from key California House races and gubernatorial primaries, according to the Associated Press and CNN.

California governor primary results

The open primary for governor was crowded field. Voters saw 61 gubernatorial candidates on their ballots in the state's closely-watched nonpartisan "jungle" primary. As of early Wednesday, it was not yet determined which two candidates would advance to the November race.
