State legislative primary contests drop 15% from 2022 midterm levels
There were 1,994 contested state legislative primaries in 2026, down 15% from the 2022 midterm cycle and representing 18% of all possible primaries. Democratic primaries increased 7% to 876, while Republican primaries fell 27% to 1,009. California had the highest share of contested primaries at 51%, while Connecticut had the lowest at 3%.
The 2026 midterm cycle produced 1,994 contested state legislative primaries across 46 states, accounting for 18% of the 11,164 possible contests. That total was 340 fewer than in 2022, a 15% decline. The share matched the 18% average observed from 2010 through 2024, though among midterm years since 2010, only 2014's 16% was lower.
Party trends diverged sharply. Democratic primaries increased 7% to 876, still below the 1,048 average for that party since 2010. Republican primaries fell 27% to 1,009. Geographic variation was pronounced: California led with 51% of primaries contested, while Connecticut had the smallest share at 3%.
Fewer contested primaries could mean voters in many states face narrower choices during nominating contests, potentially dampening turnout and engagement in 2026. The sharp Republican decline may reflect consolidation around incumbents or reduced candidate recruitment, while the Democratic uptick could signal heightened intraparty competition. Wide state-level variation—from California's 51% to Connecticut's 3%—may stem from differing filing rules, district competitiveness, and local political cultures. These patterns could shape which candidates advance to general elections and how representative nominees are of their party bases.
