Lawmakers speak out against closed, single-party primaries limiting voter choice
Some lawmakers are speaking out against closed, single-party primaries, which they see as limiting voter choice and incentivizing party loyalty over political judgment.
Objective Facts
Some lawmakers have begun to speak out against closed, single-party primaries, which they see as part of a system that limits voter choice and incentivizes elected officials to prioritize party loyalty over their own political judgment. In just the past several weeks, GOP primary voters in places like Indiana, Kentucky and Louisiana have forced out state and federal lawmakers who crossed President Trump, including on redistricting. The mid-decade redistricting efforts initiated last year by Trump have further reduced the number of competitive U.S. House districts, with more than 90% of seats now considered relatively safe for one party or the other, meaning that primaries determine nearly all U.S. House members. Nick Troiano, executive director of Unite America, has been pushing for states to hold nonpartisan primaries, warning that the mix of partisan gerrymandering and partisan primaries would lead to increased polarization in Congress. Sen. Lisa Murkowski, R-Alaska, won reelection as the only Republican senator who backed Trump's impeachment to win reelection, buoyed by Alaska's open, top-four primary system.
Left-Leaning Perspective
John Opdycke, founder and president of the group Open Primaries, told NPR that there has been "a ratcheting up, a ramping up of both the willingness and the ability of both the Democrats and the Republicans to shape outcomes before the voters get a chance to have a say," describing this as "devastating". NPR's reporting on Nick Troiano, executive director of Unite America, and other reformers warned that the mix of partisan gerrymandering and partisan primaries would lead to increased polarization in Congress. Opdycke argues that closed primaries disincentivize lawmakers from opposing sides from even working across the aisle on specific issues like energy and education because "the primary structure punishes any kind of collaboration". Rep. Brian Fitzpatrick, R-Pa., told NPR in April that closed primaries prevent doing "the right thing and supporting the right policy because of politics," saying "it's hurting our country". Research from USC found that both open primaries and top-two primaries produce less extreme lawmakers compared to closed primaries. Left-leaning reform advocates emphasize voter disenfranchisement and the removal of moderate candidates. Unite America's analysis notes that more Americans identify as politically independent than as Democrats or Republicans, yet millions of independents are disenfranchised by closed primaries where turnout is low and ideological special interests hold outsized sway. The coverage omits or downplays counterarguments about party autonomy or practical concerns about "raiding" primaries, focusing primarily on the polarization angle.
Right-Leaning Perspective
Republicans in states including Louisiana, Wyoming, Colorado, Tennessee and Texas have been pushing new limits on party primaries, in an effort to have more ideological purity among their nominees. A political science professor noted that Republicans want a system that weeds out candidates who aren't conservative enough — or what they call "RINOs". In a 2023 article for the American Conservative, Chris Tohir argued that closed primaries do not disenfranchise voters; instead, they prevent non-party members from sabotaging the electoral process. Wyoming Secretary of State Chuck Gray, a Republican, said that non-party members shouldn't vote in party primary elections because "it dilutes our primary system" and "creates incentives for people who don't share a party's values to nonetheless prevent voters of that party from electing a candidate that represents the party's platform". Defenders of closed primaries argue that public funding of election administration doesn't require parties to abandon their right to control their own nomination processes. Right-leaning coverage and analysis emphasize party autonomy and the prevention of "crossover voting" or "raiding." The framing centers on parties' rights as private organizations to control their membership and nominees. This perspective downplays concerns about independent voter exclusion or polarization effects, treating primary closures primarily as a defensive mechanism against tactical voting.
Deep Dive
The debate over closed primaries reflects a deeper tension about what primary elections are and whom they serve. With more than 90% of House seats now considered safe for one party or the other, primaries effectively determine election outcomes in most districts, making the question of primary access consequential. Both Republicans and Democrats have in recent years worked to control their primary systems, with Republicans seeking closure and some Democrats recently following suit, indicating both parties strategically benefit from limiting participation. The left's case rests on two pillars: democratic fairness and empirical evidence about polarization. Research shows that open and top-two primaries produce less extreme lawmakers, with top-two systems reducing legislator extremity by nearly double the amount that open primaries do. This is compelling evidence, though some studies find little difference compared to open systems, suggesting other factors like gerrymandering and geographic sorting play larger roles. The right's case emphasizes parties' constitutional rights to control their membership and protect against "raiding," which has legitimate precedent in campaign law. What each side misses: The left doesn't adequately address why parties would voluntarily cede control or how primary-system reform interacts with gerrymandering (the evidence suggests both matter). The right doesn't substantively engage with the empirical evidence on polarization or acknowledge that 16.6 million independent voters cannot participate in consequential elections. In 2024, voters in a number of states rejected ballot measures that would have created nonpartisan primary systems, in a significant blow to reform movements, indicating the public debate itself remains unsettled. What to watch: Starting in 2026, Louisiana will have closed primaries for congressional elections, providing a natural experiment on whether the shift increases or decreases polarization in that state's delegation.
