Seven Primaries That Could Tear Democrats Apart In 2026

With the 2026 midterms fast approaching, seven intense Democratic primary contests are taking shape across the country and highlighting divisions regarding the future of the party.

As Democrats look to reclaim control of Congress after Republican gains in 2024, several key battles could play a decisive role in determining the party’s chances at earning a majority in either chamber.

In California, the race to replace Governor Gavin Newsom is heating up, with a matchup between former Democratic Rep. Katie Porter and current Rep. Eric Swalwell taking center stage.

Porter opted not to seek reelection to her House seat in 2024, instead running for Dianne Feinstein’s open U.S. Senate seat. She finished third behind Democrat Adam Schiff and Republican candidate and former professional baseball player Steve Garvey. She is now mounting a statewide comeback with a bid for governor.

A series of videos showed Porter lashing out at a reporter during an interview and berating a staff member, opening the door for another Democrat to enter the race. California Rep. Eric Swalwell stepped into the breach in November, positioning himself as the candidate that will be a “fighter and protector.”

The two, however, risk splitting the Democratic vote, as California uses a top-two open primary system. All candidates appear on the same ballot and the two highest vote-getters advance to the general election, regardless of party. A recent poll showed how the intra-party fight between Porter and Swalwell is benefiting Republican candidates.

An Emerson College poll from December shows two Republican gubernatorial candidates, Riverside County Sheriff Chad Bianco and former Fox News host Steve Hilton, in a virtual three-way tie with Swalwell. It’s possible that if Democratic support doesn’t coalesce around either Porter or Swalwell, voters in the deep blue state could be choosing between two Republicans in the general.

Just north of Sacramento, another competitive race is emerging to fill Democratic California Rep. Nancy Pelosi’s congressional seat, after she announced she will not seek reelection ahead of the 2026 midterms. Pelosi has represented the San Francisco area for 20 terms and has served twice as Speaker of the House.

Pelosi served as a key foil to the Democratic ‘Squad’ while serving as speaker, and her exit opens the door for the far left of the party to consolidate more power. Neither candidate vying to replace her carries the experience of a longtime political tactician like Pelosi, and both boast far more progressive policy platforms.

California State Senator Scott Wiener, who has represented much of San Francisco in the state Senate since 2016, has announced his candidacy for the 11th congressional district.

Wiener previously authored a 2019 bill aimed at reducing certain sex offender registry requirements in the state, calling the existing policy “blatant discrimination against LGBT young people regarding California’s sex offender registry.”

Wiener initially said he would not challenge the former speaker for her seat, yet he announced a campaign shortly before Pelosi revealed she would be retiring. He explained that the move was necessary after Saikat Chakrabarti — former chief of staff to Rep. Alexandria Ocasio-Cortez and co-founder of Justice Democrats — launched a self-funded bid for the seat, reshaping the primary dynamics, according to a CNN report.

Chakrabarti had announced his challenge to Pelosi earlier in 2025, campaigning on a progressive platform that includes Medicare-for-All, affordable housing, and higher taxes on billionaires.

The former chief of staff had previously helped orchestrate Ocasio-Cortez’s 2018 upset victory, played a key role in drafting and promoting the Green New Deal, and worked on Bernie Sanders’ 2016 presidential campaign — experience he now highlights as central to his political credentials.

On the East Coast in Maine, a heated Democratic Senate primary is underway between establishment party candidate and current Maine governor Janet Mills, who has the backing of the Democratic political machine, and “working-class” candidate Graham Platner. Both are aiming to unseat current incumbent Republican Maine Sen. Susan Collins.

Mills, if elected, would be one of the oldest freshman senators at 77 years old, and is currently under fire for supporting taxpayer-funded health care for illegal immigrants and defying President Donald Trump’s executive order to prohibit men from competing in women’s sports.

Platner, a political first-timer who has become a progressive darling, is angling his campaign around Democratic populist policies like Medicare-for-All, labor protections, climate action, and anti-corruption reforms.

He’s been drawing large crowds, even as he faces controversies over past social media posts and a tattoo that resembled a Nazi symbol which he had covered up. (RELATED: DUKE: Nazi Tattoo Coverup Can’t Hide The Oyster Farmer’s Contrived ‘Working-Class’ Act)

In Maine, another significant race is unfolding in the state’s 2nd Congressional District following Rep. Jared Golden’s surprise announcement that he will not seek reelection.

Before Golden bowed out on Nov. 5, State Auditor and former Secretary of State Matt Dunlap had already launched a primary challenge on Oct. 6, criticizing Golden’s moderate record and his frequent alignment with Republicans. It marked the first primary challenge Golden had faced since 2018. (RELATED: Lefty Democrats Purged Their Only Congressman Without Trump Derangement Syndrome)

Prior to ending his campaign, Golden released polling indicating that he had the best shot at holding the seat for Democrats — and his exit suggests Democrats will have to dump a lot more money into the race than anticipated.

In that poll, Dunlap was trailing former Republican Maine Governor Paul LePage by 10 points, according to a NOTUS report.

Dunlap is not the only Democrat trying to replace Golden. Jordan Wood, a former chief of staff to Katie Porter and vice president at End Citizens United, initially launched a campaign for Collins’s Senate seat, but shifted to the race for the 2nd Congressional District on Nov. 12 shortly after Golden announced he would not seek reelection.

He comes to the race with Washington experience and is significantly younger than the 61-year-old Dunlap.

The first-time candidate has centered his campaign on economic issues affecting working families and already has a $1 million war chest from his Senate campaign.

Down in the Longhorn state, Texas Rep. Jasmine Crockett announced her run for Republican Sen. John Cornyn’s seat in the final hours of the filing period. Her entry into the Democratic primary roiled the party, with former Rep. Colin Allred suspending his campaign and opting to run for a North Texas congressional seat against an incumbent Democrat.

Crockett will go up against State Rep. James Talarico, a former middle school teacher and Presbyterian seminarian.

Talarico’s campaign platform is based on his fight as a state representative leading the “fight against the billionaire mega-donors and puppet politicians.” He says he is now running to fight against “corruption” in Washington and “win back power for working people,” according to his campaign website. (RELATED: Jasmine Crockett’s Vain Senate Run Already Tearing Democrats Apart)

Crockett’s entry into the race threatens to take a potentially competitive state off the table for Democrats. She has expressed that she has no intention of trying to win over Trump supporters and is running on an unabashedly progressive platform, compared to Talarico’s left-populist agenda. Yet her loyal left-wing base makes her a strong contender to win the primary.

In fact, Crockett is seen as so toxic that Republicans reportedly goaded her to run so they could better protect the seat.

The National Republican Senate Committee (NRSC) began testing Crockett’s name in internal polling in July, as first reported by the Daily Caller News Foundation. The results showed her leading a hypothetical Democratic primary. In the months that followed, the NRSC quietly encouraged Crockett to enter the race, a push that ultimately led her to join the Senate Democratic primary at the last minute.

GOP insiders believe either the incumbent Cornyn or Attorney General Ken Paxton would breeze to victory against Crockett, allowing them to save valuable resources for other races throughout the country.

In Massachusetts, Democratic Rep. Seth Moulton, is making generational change the centerpiece of his campaign against incumbent Sen. Ed Markey. Moulton argues that Democrats need new leadership after the 79-year-old senator’s nearly half-century in Congress — Markey would be 86 at the end of another term if reelected.

Moulton, a 47-year-old former Marine, previously beat incumbent Rep. John Tierney in 2014 and voted to block Democrat California Rep. Nancy Pelosi from becoming speaker of the House in 2018, according to a Politico report.

Moulton has faced backlash in his overwhelmingly blue state for tacking to the center. He suggested that his party’s recent electoral setbacks were tied to its stance on allowing transgender girls to compete in girls’ sports, according to a New York Times report.

His comments prompted his campaign manager to resign, drew a public rebuke from the state’s Democratic governor, and even led a Tufts University political science chair to threaten to stop sending students to intern in his office.

Markey — often viewed as more progressive than the moderate, reform-minded Moulton — has indirectly rejected claims he is too old to run for reelection, highlighting his alleged energy, fresh ideas, and commitment during crises like the government shutdown.

Following mayor-elect Zohran Mamdani’s victory in New York City, Democrats are now turning their attention to holding the governor’s office in the Empire State.

Incumbent Democrat New York Gov. Kathy Hochul, who previously served as lieutenant governor under former Gov. Andrew Cuomo and assumed the governorship in August 2021 following his resignation, is running to maintain her residency in Albany. (RELATED: Hochul’s Lead Over Stefanik Falls After Record Comes To Light: POLL)

She made a late appearance alongside Mamdani in his mayoral campaign, publicly throwing her support behind him and pointedly snubbing Cuomo, who had launched an independent bid after losing the primary to Mamdani.

Hochul is facing a primary challenge from her own lieutenant governor, Antonio Delgado, who launched his bid in an effort to unseat Hochul in June.

Delgado spent three years in the U.S. House before Hochul tapped him in 2022 to serve as lieutenant governor, making him the first Latino to hold statewide office in New York.

In a video previewing his announcement, he appears speaking to New Yorkers across the city while calling for “universal health care,” “universal pre-K,” and pledging to fight “the Trump administration’s attacks” on deep-blue New York.

Although Hochul and Delgado began their tenure on good terms and were elected to full terms together, their relationship has cooled as they diverged on key issues, even as the Democratic Governors Association (DGA) has signaled its full support for Hochul heading into the 2026 primary.

Delgado’s public divergences with Hochul began to surface most clearly when he urged President Joe Biden to withdraw from the 2024 presidential race. After the election, he reinforced that message in a New York Times op-ed calling for the Democratic Party to change direction, concluding with the line: “A new path is both necessary and possible, but we will not chart it with the same politicians telling the same old stories. We are ready for the next generation.”

He later deepened the divide by calling for New York City Mayor Eric Adams to resign, even as Hochul adopted a more measured approach. The split over Adams prompted spokesperson Avi Small Hogrebe to issue a statement underscoring that “Lieutenant Governor Delgado does not now and has not ever spoken on behalf of this administration.”

These tensions — driven by disagreements over party loyalty, political strategy, and generational change — ultimately led Hochul to remove most of Delgado’s staff and resources, underscoring the widening rift between them, according to a Politico report.

Over the past year, Delgado has gone from a somewhat reluctant lieutenant governor to a political outcast who is no longer on speaking terms with Hochul.

Polls show the Republican frontrunner, Rep. Elise Stefanik, performing slightly better against Delgado, though neither matchup appears to be particularly competitive.

Recent special election and off-year victories for Democrats have the party convinced they’re looking at a blue wave in the 2026 midterms. Even if they are able to regain the majority in Congress, the tense fight between progressives and moderates and younger and older candidates threatens to severely bruise the Democrats in the process.
