2024 California's 16th congressional district election

The 2024 California's 16th congressional district election will be held on November 5, 2024, to elect the United States representative for California's 16th congressional district, concurrently with elections for the other U.S. House districts in California and the rest of the country, as well as the 2024 U.S. Senate race in California, other elections to the United States Senate, and various state and local elections. The primary election was held on March 5, 2024, concurrently with the Super Tuesday presidential primaries.

The 16th district is an urban/suburban district based in Silicon Valley, including portions of Santa Clara and San Mateo counties, extending from the southwestern San Francisco Bay Area through the Santa Cruz Mountains to the Pacific coast. Its largest cities are San Jose, Mountain View, and Palo Alto. Joe Biden won the district with 75.4% of the vote in the 2020 presidential election, making it a safe Democratic district.

The incumbent is Democrat Anna Eshoo, who was re-elected with 57.8% of the vote in 2022 against another Democrat. She did not seek re-election. A wide field of 11 candidates filed for the race to succeed her, with 9 Democrats and 2 Republicans joining the race. The primary election was very close, with initial returns showing a heated battle for the two spots in the general election. A week after the primary, media outlets reported that former San Jose mayor Sam Liccardo had taken the first spot. However, it was unclear which candidate he would face in the general election, as state assemblyman Evan Low and Santa Clara County supervisor Joe Simitian repeatedly traded the second-place position during the vote count process.

By April 3, both Low and Simitian tied with 30,249 votes each in the final account and were expected to advance to the general election under a stipulation by California elections code regarding a second-place tie in primary elections. However, a recount was requested by two voters shortly thereafter. The recount request was controversial, with Low's campaign accusing Liccardo of being behind it, an accusation which was vehemently denied by Liccardo's campaign. At the conclusion of the recount on May 1, Low ultimately edged out Simitian by a margin of 5 votes, with Low gaining 12 votes and Simitian 7. As required by federal law, the source of the recount funds was later revealed to be a pro-Liccardo super PAC funded almost entirely by billionaire Michael Bloomberg.

The primary results marked the second time since California transitioned to a nonpartisan blanket primary system in 2012 in which there was a second-place tie in a primary election and a potential three-candidate general election, the first being the 2016 election for California's 62nd State Assembly district.

Recount and involvement of Liccardo super PACs
Santa Clara and San Mateo counties certified the primary results on April 4. The Los Angeles Times pointed out that Low and Simitian had no incentive to request a recount, which could potentially lock them out of the general election. Both campaigns released statements indicating that they intend to compete in the general election. However, local media reported that a poll had been sent to voters testing a three-way race as well as two-way races between Liccardo and each of his opponents, leading to speculation that Liccardo's campaign would ask for a recount. On April 9, officials in Santa Clara and San Mateo counties confirmed that two residents of the district had requested a recount: Jonathan Padilla, who served as finance director on Liccardo's 2014 mayoral campaign and donated $1,000 to his 2024 congressional campaign, and Pacifica resident Dan Stegink. Stegink later withdrew his request.

Low's campaign alleged that Liccardo was behind the requests, which they called "a page right out of Trump's political playbook using dirty tricks to attack democracy and subvert the will of the voters." Liccardo's campaign denied responsibility, though they maintained the recount was necessary, saying "every vote should be counted." Padilla, a "longtime Silicon Valley political insider," did not answer questions from local media about the source of the funds for the costly recount. Eshoo, who endorsed Simitian, called for transparency in the recount process. In his recount request, Padilla wrote that he was "not coordinating or communicating with any candidate or candidates’ agents" and made "this request on behalf of Evan Low." However, Low's campaign reaffirmed that he did not support the recount and called Padilla's statement "disingenuous."

Padilla submitted a $12,000 deposit for the recount on April 12. He opted for a machine recount, in which ballots are re-screened by a machine, rather than a much more expensive manual recount, in which volunteers would count each ballot by hand. Election officials estimated the cost of the machine recount at around $80,000, whereas a manual recount could have cost upwards of $400,000. The recount began on April 15.

According to reporting by KNTV, the recount is being funded by $12,000 checks from the newly-formed super PAC "Count the Vote" signed by James Sutton, an attorney who had previously represented Liccardo. On April 19, Santa Clara County Government Attorneys Association president Max Zarzana filed a complaint with the Federal Elections Commission, alleging that the Liccardo campaign concocted a "secret scheme to illegally coordinate with a newly-formed dark money Super PAC to do his CD-16 recount bidding" and noted Liccardo's past connections with those involved in requesting the recount. Zarzana also highlighted Liccardo's history of "backroom deals" including violations of the California Public Records Act for which he was previously fined $500,000.

The results of the recount were finalized on May 1, with Low advancing to the general election and Simitian eliminated by a 5-vote margin, 30,261 to 30,256. On May 2, the Liccardo campaign shared internal poll results showing him with a 10-point lead over Low in a two-way race, compared with just a 5-point lead in a three-way race. The poll was completed on April 8, the day before the recount was requested.

On May 20, Neighbors for Results, the super PAC supporting Liccardo almost entirely funded by billionaire Michael Bloomberg, disclosed that it paid $102,000 to the group which funded the recount, Count the Vote PAC. The attorney who represented Padilla in his recount request, Matthew Alvarez, is also listed as the treasurer of both super PACs in question. In 2018, Bloomberg Philanthropies previously selected San Jose, which Liccardo was then mayor of, for funding and resources from the American Cities Climate Challenge, and two years later Liccardo then endorsed and served as a state co-chair on Bloomberg's presidential campaign. After this information was publicized, a second Bay Area attorney, Brian O'Grady, filed a FEC complaint claiming that the PACs violated federal campaign finance laws in order to hide their connection with Liccardo's campaign.
