- Bipartisanship is not dead but is now narrowly issue-specific: defense, veterans, aviation — not immigration, climate, gun safety, or healthcare
- Infrastructure (69-30), CHIPS (64-33), Bipartisan Safer Communities (65-33): each passed because business-aligned R and pragmatic D found shared interest and the political cost of blocking was too high
- The 2024 bipartisan immigration reform deal died not from policy disagreement but because Trump directed R senators to kill it — the most revealing test of the current limits
- 15% Congress approval reflects voter recognition of the dysfunction; translating that into an electoral outcome requires one party to take clear ownership of the gridlock
What Bipartisanship Actually Produced: 2021-2026
| Legislation | Year | Senate Vote | Issue Area | Republican Votes | Status |
|---|---|---|---|---|---|
| Infrastructure & Jobs Act | 2021 | 69-30 | Roads, bridges, broadband | 19 Republicans | Signed, implementing |
| CHIPS & Science Act | 2022 | 64-33 | Semiconductor manufacturing | 17 Republicans | Signed, implementing |

| Electoral Count Reform Act | 2022 | 68-29 | Election administration | 18 Republicans | Signed, law |
| PACT Act (Veterans) | 2022 | 86-11 | Veterans burn pit care | Majority of R | Signed, law |
| Border/Immigration Reform | 2024 | Collapsed | Immigration | 0 (blocked by R leadership) | Failed — Trump directed R senators to block it |
| Background Checks (Manchin-Toomey) | 2023 | 50-50 | Gun safety | Not enough for cloture | Filibustered, failed |
The Filibuster as Veto: Why 60 Matters
The Senate filibuster's 60-vote cloture threshold has been the structural veto point for most consequential domestic legislation in the modern era. It was not always this way: the filibuster was a rarely-used tool through much of the 20th century, deployed for dramatic effect on civil rights legislation by Southern Democrats. Beginning in the 1990s and accelerating through the Obama era, filibuster use became routine — a first-resort blocking mechanism rather than a last-resort dramatic statement.
The practical effect: bills with 51, 55, or even 58 votes — genuine bipartisan majorities — cannot pass unless they can reach 60. Background checks for gun purchases have consistently polled at 80-90% public support and have repeatedly passed the House. In the Senate, they have repeatedly fallen short of 60 votes because Republican senators who might personally favor the policy face primary challenger threats from gun-rights advocates if they vote for any Democratic-sponsored gun legislation. The gap between public opinion (80% support) and Senate outcomes (fail) is among the most dramatic examples of institutional veto politics in the American system.
The Immigration Gang Collapse
The 2024 bipartisan border security and immigration reform negotiations represented the most serious cross-party immigration compromise attempt in a decade. Senators Chris Murphy (D-CT), James Lankford (R-OK), and Kyrsten Sinema (I-AZ) led a framework that combined enhanced border enforcement mechanisms, including authority for the president to temporarily restrict asylum processing during surge periods, with a path to extended legal status for certain undocumented populations.
The negotiation collapsed after former President Trump, not yet the incumbent but the presumptive 2024 Republican nominee, publicly directed Senate Republicans to kill the deal because passing it would deprive him of a campaign issue. Lankford, who had negotiated in good faith and whose state of Oklahoma had border security concerns, faced intense backlash from Republican primary voters and MAGA media for having participated in the talks at all. The collapse illustrated the central dynamic that makes bipartisan governance on high-salience issues nearly impossible: the political incentive structure punishes the act of negotiating, regardless of outcome.
Where Bipartisanship Survives — and Where It Doesn't
Still Bipartisan
The National Defense Authorization Act passes annually with large bipartisan margins. FDA and NIH reauthorizations, veterans benefits, disaster relief supplementals, and some judiciary confirmations draw cross-party votes. These share a common characteristic: voting against them creates more political pain than voting for them, making the cost-benefit calculation favor cooperation. "Pocket-book" bipartisanship — keeping government running and funded — also persists at the continuing resolution level.
Completely Collapsed
Climate legislation, healthcare reform, immigration reform, campaign finance reform, voting rights, and gun safety beyond the 2022 compromise: all have become pure partisan votes where Republican senators face primary threats for any cross-aisle cooperation. These are the highest-profile domestic policy debates and the most visible to voters — meaning voters experience gridlock most acutely on exactly the issues they care most about.
The Electoral Consequence
Congress's approval rating consistently sits around 15%, reflecting deep public dissatisfaction with institutional performance. However, research consistently shows that congressional approval does not translate cleanly into electoral punishment of incumbents: voters tend to blame "Congress" as an abstraction while re-electing their own representative. The bipartisanship debate matters electorally primarily in competitive swing districts where independent voters who dislike partisan warfare can be mobilized by candidates who credibly claim to be different.
Can Bipartisanship Return After 2026?
The structural conditions that have eroded bipartisanship — sorted partisan geography, primary election dominance, the 24-hour media ecosystem rewarding conflict — show no sign of reversing regardless of which party controls which chamber after 2026. The most optimistic scenario for bipartisan governance would require: a large enough Senate majority on one side to break filibusters (60+ seats), a reduction in primary threat credibility for centrist members, and a political environment where reaching across the aisle creates positive political returns rather than primary challenges.
None of these conditions currently exist. The 2026 Senate map produces a competitive outcome in the 48-52 range regardless of which party wins, ensuring continued dependence on cross-party vote-finding or filibuster reform debates. The most likely legislative outcome of the 119th Congress (2027-2028) is a continuation of the current pattern: administrative bipartisanship on must-pass items, complete partisan gridlock on everything else, and an increasingly frustrated public that has largely stopped expecting governance from Washington on major issues.
