Americans regularly tell pollsters that Congress cannot get anything done. Major legislation still passes, often in bursts after elections or crises, but long stretches pass without action on issues such as immigration, entitlements, or the debt. Gridlock has roots in the constitutional design, in Senate rules, and in modern political trends.
This guide explains the causes of gridlock, its consequences, and the debate over what, if anything, to do about it.
The framers designed a system of separated powers and checks and balances to make lawmaking deliberate. A bill must pass the House and the Senate in identical form and be signed by the President, or survive a veto by two-thirds of each chamber. Committees, party leaders, and floor rules add more points where bills can stall. James Madison argued in Federalist No. 51 that ambition must be made to counteract ambition, and many defenders of the system see gridlock as protection against hasty or overreaching laws.
Since 1955, one party has controlled the presidency, House, and Senate together only about a third of the time. When control is divided, the opposition can block the President's agenda, though divided governments have also passed major bipartisan laws, such as the 1986 tax reform and 1996 welfare reform. Unified governments still face obstacles, since narrow majorities leave little room for defections.
When Congress does not act, Presidents increasingly govern through executive orders, emergency declarations, and agency rules, and courts resolve disputes that legislation might have settled, which can make policy swing with each administration. Proposals to reduce gridlock include changing the filibuster, budget process reforms, open primaries and ranked-choice voting, redistricting reform, and automatic continuing resolutions to prevent shutdowns. Others argue that gridlock reflects a genuinely divided country and that the remedy lies in persuading voters rather than changing rules.
Congress has passed all regular appropriations bills on time only a few times since the current budget process began in 1976 and relies instead on continuing resolutions and large omnibus bills. Funding lapses have caused government shutdowns, including the 35-day shutdown of 2018 and 2019 and the 43-day shutdown in October and November 2025, the longest in history, and a 76-day lapse in Homeland Security funding in 2026. Debt ceiling standoffs have repeatedly raised the risk of default. Recent Congresses have enacted fewer laws than any in decades. As of mid-October 2026 the 119th Congress had enacted 121 public laws, the second-fewest at that point in four decades, after the 118th.
The parties have become more ideologically uniform and distant from one another since the 1970s, and the number of moderates has shrunk. Safe districts and primaries reward members who appeal to their party's base. Control of Congress has changed hands often, and narrow majorities give each party an incentive to deny the other accomplishments before the next election. House majorities sometimes avoid bills opposed by most of their own members, an informal practice known as the Hastert rule.
Because ending debate on most legislation in the Senate requires 60 votes, the minority party can block bills supported by a majority. Filibuster use rose sharply after 2006. Major laws are often passed through budget reconciliation, which needs only a simple majority but is limited to taxes, spending, and the debt limit, as with the 2017 tax law and the 2025 tax and spending law. Senators also place holds on nominations and bills. The Senate eliminated the filibuster for nominations in 2013 and 2017 but has kept it for legislation.
