2024 United States Senate elections in California#Democratic Party

California is considered to be a safe blue state at the federal and state levels, with Joe Biden winning the state by a margin of 29.16% in the 2020 presidential election. Democrats currently hold a large majority in California's U.S. House delegation, all statewide offices (including both U.S. Senate seats), and supermajorities in both of California's state legislative chambers.

Prior to the 2024 election, senator Dianne Feinstein had served in Congress since being elected in a 1992 special election, defeating Republican appointee John Seymour. During her career, she was re-elected five times, winning in 1994, 2000, 2006, 2012, and most recently in 2018, where she defeated fellow Democrat Kevin de León with 54.2% of the vote. At the time of her death, Feinstein was the most senior Democrat in the Senate, and is the longest serving U.S. senator in California's history.

Media sources speculated for years that Dianne Feinstein might choose not to seek reelection in 2024 or resign before the end of her term, owing to her age, reports that her cognitive state was declining, and her decision not to take the position of Senate president pro tempore in the 118th Congress, third in line for the presidency, even though she would customarily have been offered the role as the most senior member of the majority caucus. There was also speculation that Feinstein might face opposition within the Democratic Party as she did in 2018, when she was challenged by fellow Democrat Kevin de León and defeated him by an unexpectedly narrow margin.{{cite news |date=November 18, 2022 |title=California's 2024 U.S. Senate race could be a hot one |work=The Los Angeles Times |last=Willon |first=Phil |url=https://www.latimes.com/california/newsletter/2022-11-18/la-me-pol-california-politics-newsletter-feinstein-senate-ca-politics}} In December 2022, Feinstein confirmed that she would not resign before the end of her term.{{cite news |url=https://www.latimes.com/politics/story/2022-12-12/feinstein-says-she-wont-step-down-early-from-senate |title=Feinstein says she won't step down early from Senate |date=December 12, 2022 |last=McCaskill |first=Nolan |work=The Los Angeles Times}}

In January 2023, with the question of Feinstein's reelection decision still open, U.S. Representative Katie Porter announced that she would run for the Senate. She confirmed that she would stay in the race even if Feinstein chose to run for another term. Porter was first elected in 2018, unseating incumbent Mimi Walters. She later gained national fame for her progressive politics, and frequently went viral online for her pointed questioning of corporate executives in congressional hearings, often while using a whiteboard.{{cite news |url=https://www.ocregister.com/2023/01/10/rep-katie-porters-most-viral-moments-in-congress/ |title=Rep.

Lee, Porter, and Schiff have similar voting records in Congress and similarly progressive platforms. As a result, they were expected to differentiate themselves by their life stories and individual strengths rather than their ideologies. All three have faced controversies that could damage their campaigns: Porter has been accused of mistreating congressional staff, Lee's age was seen as a potential issue, and Schiff was expected to face opposition from progressives due to his past support for overseas military intervention and for taking donations from groups affiliated with the oil, payday loan, and pharmaceutical industries, though he took a no corporate PAC pledge in his Senate campaign.{{Cite web |url=https://www.politico.com/newsletters/women-rule/2023/01/13/katie-porters-bad-boss-problem-00077874 |title=Katie Porter and the 'bad boss' problem |first=Katelyn |last=Fossett |website=Politico |date=January 13, 2023 }}{{cite news |url=https://www.latimes.com/politics/story/2023-02-20/democrats-feinstein-porter-schiff-lee |title=These Democrats hoping to replace Feinstein largely agree on policy.

Schiff began 2023 with $20.6 million in his campaign account compared to $7.7 million for Porter and just under $55,000 for Lee.{{Cite web |url=https://www.bloomberg.com/news/articles/2023-01-27/2024-california-senate-race-is-off-to-expensive-start-as-schiff-porter-join |title=California's Crowded Senate Primary Race Is Set to Be Most Expensive in History |date=January 27, 2023 |work=Bloomberg |last1=Davison |first1=Laura |last2=Breslau |first2=Karen}} All three quickly began raising large sums of money; for example, in the first 24 hours of her campaign, Porter raised over $1.3 million.{{Cite web |url=https://thehill.com/homenews/campaign/3808858-porter-rakes-in-1-3m-in-first-24-hours-of-senate-bid/ |title=Porter rakes in $1.3M in first 24 hours of Senate bid |first=Max |last=Greenwood |date=January 11, 2023 |work=The Hill}} The three also launched super PACs to aid with fundraising, each competing for the top California fundraising firms and consultants.

Throughout most of 2023, there were no prominent Republicans in the race. This has been attributed to California's heavy Democratic lean and Republican donors' wariness of the high cost of running a statewide campaign in California; GOP strategist Duane Dichiara estimated that a Republican would need at least $80 million to run a viable Senate campaign. Additionally, California's top-two primary system could have allowed two Democrats to advance to the general election, a scenario that played out in the 2016 and 2018 Senate races, though the three-way division in the 2024 Democratic field could have helped a Republican reach the general election. Republicans would also benefit from the fact that the 2024 California Republican presidential primary, held on the same day as the Senate primary, was expected to be hotly contested and entice Republican voters to turn out in higher numbers.{{Cite web |url=https://www.latimes.com/politics/story/2023-03-10/california-republican-party-convention-senate-congress-feinstein-mccarthy |title=California Republicans, buoyed by congressional wins, have no obvious Senate prospects |date=March 10, 2023 |website=Los Angeles Times |last=Mehta |first=Seema}}

On October 10, 2023, Republicans gained a prominent candidate when former professional baseball player Steve Garvey entered the race. Garvey, who played for both the Los Angeles Dodgers and the San Diego Padres, was considered to have an advantage in name recognition. Two other Republican candidates, healthcare executive James Bradley and attorney Eric Early, both of whom had previously made several unsuccessful bids for office, also attracted some media attention and support in polls.

Schiff and Porter consistently led in polling throughout the race, with Lee and the Republicans far behind. Lee's poor polling numbers was attributed to a lack of name recognition outside her San Francisco Bay Area constituency, her lack of fundraising compared to Schiff and Porter, and the fact that Schiff and Porter had prior national fame while Lee was less well-known. In November 2023, Lee ruled out withdrawing from the race and insisted she still had a chance.{{cite news |work=The Sacramento Bee |date=November 13, 2023 |access-date=November 19, 2023 |author=Holden, Lindsey |title=Barbara Lee trails badly in California Senate race.

The Gaza war became a late issue in the race, with Lee initially being the only major candidate to call for a ceasefire. The California Democratic Party convention was disrupted by pro-Palestine protests calling for a ceasefire. Protestors entered the main convention arena and shouted, interrupting speeches by Schiff, Porter, and Lexi Reese.

After her loss, Porter remarked that the election was "rigged by billionaires," referring to a $10 million independent ad campaign attacking her that was funded by cryptocurrency supporters.{{Cite news |last=Lightman |first=David |title=Katie Porter continues to claim billionaires 'rigged' California Senate primary |url=https://www.sacbee.com/news/politics-government/election/california-elections/article286386800.html |access-date=2024-03-10 |work=Sacramento Bee |language=en}} Porter's use of the word "rigged" was criticized, with some comparing her statement to Donald Trump's true claims of fraud in the 2020 election. Porter expressed regret for use of the word "rigged" and said that she meant to say that the election was "manipulated by dishonest means" which was a reference to the use of dark money in campaign financing, and not to mean that there was anything illegitimate about the vote counting.{{Cite web |date=2024-03-08 |title=Katie Porter faces backlash after claiming California Senate race was 'rigged' |url=https://abc7.com/katie-porter-says-california-senate-race-was-rigged-faces-backlash/14503858/ |access-date=2024-03-10 |website=ABC7 Los Angeles |language=en}}{{cite news|url=https://thehill.com/homenews/house/4541839-porter-regrets-saying-california-senate-primary-race-was-rigged/|title=Porter regrets saying California Senate primary race was 'rigged'|date=March 19, 2024|first=Hanna| last=Trudo|work=The Hill}}
