2026 Democratic Primary

Montana’s 2026 election cycle remains an uphill battle for Democrats in a state that has consistently favored Republicans in federal races. Still, Democrats are fielding candidates in both U.S. House districts and the U.S. Senate contest, aiming to compete through grassroots organizing, rural outreach, and working-class economic messaging in hopes of improving margins and testing the state’s political trajectory in a midterm year.

Michigan will be one of the most competitive Democratic Senate primaries of the 2026 cycle following Senator Gary Peters’ decision to retire and not run for re-election. As a battleground state that has flip-flopped in recent federal elections, Michigan’s Senate seat is a top priority for the Democrats. In order to win, Democratic nominee will need to garner support from the party’s urban voter base, perform well in suburban areas, and furthermore perform well with working-class voters all across the state.

Shifting to the Pine Tree State, Maine features one of the most consequential Senate races for Democrats in 2026, alongside two U.S. House contests. The primary will be June 9th followed by the general on November 3rd.

In Kentucky, the Bluegrass State, voters will decide one U.S. Senate race and all six U.S. House seats in 2026. The marquee contest follows the retirement of Mitch McConnell, ending decades of Republican leadership in Washington. McConnell’s tenure included serving as Senate Majority Leader and playing a central role in shaping the modern federal judiciary. His relationship with former President Donald Trump deteriorated following the January 6th attack on the U.S. Capitol, limiting his standing within the party’s populist wing, but his institutional influence remained significant through the end of his career.

For a state that is often considered a Republican stronghold, Louisiana has more political complexity than a surface-level glance. It certainly leans red; that much is sure given the state has voted for the Republican candidate in every presidential election since 2000 and Republicans hold nearly every statewide elected office and a majority in the statehouse. With Republican Governor Jeff Landry elected in 2023, the state has pushed further and further right on issues regarding abortion, education, and immigration. However, there is an interesting political divide between Republican rural areas and urban Democratic strongholds like New Orleans. Notably, there is a 37%-35% split when it comes to registered Democrats and Republicans respectively, meaning that in most recent elections, some registered Democrats are voting for Republican candidates.

Indiana can be considered a relatively safe Republican stronghold. Both the senators from the state are Republicans, and only 2 of the 9 representatives are Democrats. This year, neither Senator Todd Young nor Senator Jim Banks are up for election, but the house is a different story. All nine seats are up for grabs in theory, although most seats are drawn in a way that all but ensures the current party makeup from changing. That didn’t stop President Donald Trump from trying, however, as late last year he urged the state of Indiana to redraw its congressional districts to unseat incumbent Democrats Frank Mrvan of the 1st district and André Carson of the 7th district. Despite a Republican-supermajority in the Senate, a Trump vow to primary Republican holdouts, and anonymous bomb threats, the measure failed and the maps remained unchanged.

The Democratic Party in Idaho is implementing an expanded strategy aimed at competitive races in 2026. The Idaho Democratic Party recently launched its “All In for Idaho” campaign to recruit local candidates and grow voter registration, especially in rural and traditionally conservative communities that have often been overlooked.

Kansas has one Democratic member of the house up for re-election Sharice Davids of the 3rd Congressional District.

In 2026, Iowa will see one Senate race & four House races in its congressional elections. The Hawkeye state has been a Republican stronghold since Trump came on the scene in 2016, but the Cook Political Report currently has two of Iowa’s House seats as toss-ups. In a year where Democrats should be expected to overperform, we could see Hawkeye voters change the distribution of the state’s legislative power in Washington. Currently, all 6 of Iowa’s congressional seats are held by Republicans, but 2026 could see one, if not more, of these change. Voters will be able to cast their ballots in the primary on June 2, 2026 & in the general election on November 3, 2026.

The Aloha state will feature two House races but will be absent a headlining Senate race. Senior Senator Brian Schatz will be back up for re-election in 2028 & the Junior Senator Mazie Hirono will be back up in 2030. Overall, the state is solidly Democratic, with all four members of Congress under the Democratic banner. Further, at the state level, of the 51 state house members, only 9 are Republicans. That means the remaining 42 are Democrats since no Independent has a seat in the Hawaii State House. In the Hawaiian Senate, the breakdown is 3 Republicans to 22 Dems. Hawaii is a solidly blue state, & the real campaign or battle will be in the Democratic primaries.

Announced Delaware Democrat Senate Candidates: Chris Coons (incumbent) and Christopher Beardsley. Announced Delaware Democrat House Candidates: Sarah McBride (incumbent). The primary elections will take place on September 15, with the general election happening on November 3rd.

Connecticut, known as the Constitution State, will feature five U.S. House races in 2026, with no U.S. Senate contests on the ballot. Both of the state’s U.S. Senators, Richard Blumenthal and Chris Murphy, are midway through their six-year terms, having last been elected in 2022 and 2024, respectively.
