Incumbent Devin Nunes (R) and Phil Arballo (D) advanced to the Nov. 3 general election for California’s 22nd Congressional District, defeating three other candidates in the March 3 top-two primary. As of March 11, Nunes had received 56.9% of the vote to Arballo’s 24.8%. The only other candidate with more than 10% of the vote was Bobby Bliatout (D), with 12.7%.
One Democrat and one Republican have advanced from the district’s primary in each congressional election since California’s top-two primary system went into effect in 2011. Three Democrats and one candidate with no party preference ran in addition to Nunes, who was first elected in 2002.
All 435 House districts will be up for election on Nov. 3, 2020, and the results will determine the partisan balance of the U.S. House in the 117th Congress. As of March 2020, Democrats have a 232-197 advantage over Republicans. If Republicans win 18 Democratic-controlled districts, they will win control of the House. If Democrats hold as many districts, they will maintain their control of the chamber.
