CA-43 primary: Who will advance?

Maxine Waters consistently demonstrates strong electoral performance in her district. She has a well-established history of successfully advancing in primary elections and securing general election victories in California's 43rd Congressional District, a reliable Democratic stronghold ^{[5][6][2][7][1][8][9]}. Recent examples include her advancement alongside Steve Williams in the March 2024 primary, followed by a general election win, and similar victories in the June 2022 and March 2020 primaries ^{[5][6][2][7][1][9]}. Since taking office in 1991, her re-election margins frequently exceed 70% of the vote, underscoring her strong political base ^[10]. The district's Democratic leanings are evident, with Joe Biden receiving 80.8% of the vote in the 2020 presidential election following redistricting, compared to Donald Trump's 17.0% ^[2][1].

Robust fundraising consistently reinforces Waters' strong political standing. Throughout her career, she has raised over $5.1 million across her campaigns, a hallmark of her consistent financial support from diverse sources ^{[3][11][12][13]}. For the upcoming 2026 election cycle, Waters has already begun receiving contributions from various Political Action Committees (PACs), including The Bank of New York Mellon Corporation-Federal, Chime Financial, and Visa, Inc. ^[14]. An April 2025 FEC disclosure further indicated $19,300 in new fundraising during the first quarter of 2025, leaving her with $166,400 in cash on hand at the close of that filing period ^[4].

Myla Rahman has reported significantly higher campaign receipts compared to Cristian Morales for the CA-43 top-two primary. As of March 31, 2026, Myla Rahman's campaign recorded $14,540 in receipts and maintained $5,367 cash on hand. In contrast, Cristian Morales reported $0 in receipts, and his cash on hand was not available or was zero for the same period ^[1][2].

Specific details on endorsements and prediction market probabilities are unavailable. While Ballotpedia notes that both Myla Rahman and Cristian Morales are gathering endorsements, no populated lists or counts have been provided ^[2][3]. Similarly, existing prediction markets for the CA-43 primary on platforms like Kalshi and Robinhood do not include candidate-specific implied probabilities for Myla Rahman versus Cristian Morales in the currently available information ^[4][5][6].

Challengers must differentiate from incumbents and broaden their appeal in top-two primaries. In California's 43rd Congressional District, challengers like Myla Rahman or Christian Morales must strategically distinguish themselves from incumbent Maxine Waters to appeal to a broad voter coalition ^{[5][6][1][2][7]}. The top-two primary system allows two candidates from the same party to advance, necessitating that challengers appeal beyond their partisan base ^[1][2][3]. A critical step involves researching the incumbent's voting record to identify vulnerabilities and proposing concrete, actionable solutions to local issues such as economic development, housing, crime, or education ^[7][8][9]. Establishing a clear contrast by highlighting unique qualifications and experiences is crucial, presenting voters with a distinct choice rather than simply criticizing the incumbent ^[7][8][9]. An early and consistent campaign, delivering an understandable message, is vital for achieving voter recognition and building trust ^[8].

Grassroots outreach and targeting NPP voters are crucial for consolidation. Consolidating the non-Waters vote requires intensive grassroots mobilization, including community events, town halls, and direct voter contact across diverse neighborhoods within the district ^[7]. Given the district's demographics, outreach efforts should incorporate non-English languages where appropriate to reach all constituents ^[10]. Challengers must target 'No Party Preference' (NPP) voters, who are often ideologically moderate and represent a critical voting bloc in top-two primaries ^[3][4]. Appealing to their pragmatic concerns with common-sense solutions can help build support beyond traditional partisan lines ^[3][4]. Minimizing highly partisan national rhetoric is important to avoid alienating potential crossover voters ^[3]. For instance, Rahman could position herself as a more progressive or a more moderate, locally-focused Democrat, potentially resonating with younger demographics ^[7][11][12]. The presence of multiple challengers, such as David Sedlik (D), will inherently make voter consolidation more difficult ^[13].

No specific public polling data is available for the CA-43 primary. As of current research, no public polling data has been identified for the California 43rd congressional district primary, which is scheduled for June 2, 2026 ^[1][2][3]. The known candidates for this primary include Maxine Waters, Cristian Morales, Myla Rahman, and David Sedlik ^[2][3].

The 43rd district exhibits strong Democratic leanings and incumbent support. The district's political leanings are strongly Democratic, with a Cook Partisan Voting Index (PVI) of D+27 ^[3][4]. In the previous primary election, incumbent Maxine Waters secured a significant victory, winning 69.8% of the vote ^[3][4]. Polling data for nearby districts like CA-48 and CA-40 is available, but does not pertain directly to CA-43 ^[1][5].

Prediction markets offer insights despite the absence of traditional polling. Despite the lack of traditional polling, prediction markets are available for the 'CA-43 primary: Who will advance?' on platforms such as Robinhood and Kalshi ^[6][7]. For the general election, markets also indicate that Democrats are heavily favored to win the CA-43 House seat ^[8].

Maxine Waters' age and long tenure create an opening for challengers. Waters' extensive incumbency since 1991 and her current age, 87, are identified as primary factors challengers are using to argue for "generational change" in the 2026 CA-43 primary ^[2]

Explicit age-related concerns question her effectiveness, particularly regarding chairing a powerful committee, given she would be in her late 80s or 90s by the conclusion of a potential new term ^[1].

The June 2, 2026, top-two primary election in California's 43rd Congressional District, where filing closed on March 6, 2026, could be a key catalyst in the race ^[1][2][3][4]. Incumbent Maxine Waters (D), who was first elected in 1990 and is 86 years old, received 69.8% in her last primary election ^[4][5]. The district is rated Solid/Safe D by Cook and Sabato, with Democrats holding 93% odds to win the seat on Polymarket ^[3][4][6].

With a crowded field including more than five Democratic challengers and two to three Republican challengers, the primary could be dynamic ^[3][7]. As of May 2026, no polls or primary-specific market odds have been found, indicating a potential for shifts in perceived probabilities as the primary date approaches ^[8][9]. The district's demographics, with 57% Hispanic and 24% Black populations in South LA, are also a factor in the electoral landscape ^[10].
