Congress still has work to finish after November 3. Members who lose keep their votes until new terms begin January 3, so the current Congress handles every year-end deadline. That agenda falls into three groups: measures needed to keep government and essential programs running, bills under heavy pressure to pass and deals that would be useful to finish.

The election changes the order within those groups. Funding and essential extensions are necessary under every result, but leverage shifts. Nominations jump to the top of the Republican list if Democrats win the Senate, and permitting moves up if Republicans lose either chamber.

Democrats win both chambers. Republicans will press to lock in priorities before losing the agenda. Democrats can insist on short extensions and save the larger bills for their own committee chairs in January. Trump remains president, which limits how much Democrats gain by waiting on a compromise he would sign.

Democrats win one chamber. Republicans lose unified control next year, so expect more bargaining: incoming Democrats demanding concessions, Republicans pushing for more policy and longer extensions before their position weakens. If Republicans lose the Senate, expect nominations to become a critical priority for both Republicans and the White House.

If Republicans keep both chambers, the main difference is less pressure to rush: leaders could handle funding and leave harder fights for 2027.

Margins matter under every result. A narrow outcome leaves more unfinished work for the lame duck; a clearly larger majority leaves the losing side little leverage. Departing members add uncertainty because they keep their votes without facing voters again. An election loss creates urgency; it does not mean losing members have to participate.

Government funding, December 11. Temporary funding runs out December 11. Without a replacement, affected agencies shut down, with furloughs and delayed federal pay. A temporary extension into 2027 is the likely starting point after Democratic gains, since the winners want a say in the annual budget. If Democrats win only one chamber, Republicans have more reason to settle the full budget in December, while Democrats have more reason to wait.

Senate Appropriations Chair Susan Collins (R-ME) favors bipartisan annual spending bills that give agencies firmer budgets, and she faces voters herself in November. The House Freedom Caucus, in a November 2025 statement posted by Rep. Andy Harris (R-MD), backed a long temporary extension to hold spending flat and avoid a large year-end package.

Transportation, flood insurance and veterans’ care, December 11. The same law extended highway and transit programs, the National Flood Insurance Program and nursing-home and rural ambulance protections for certain veterans. A lapse would interrupt federal reimbursements states use for road projects, generally block new flood policies and renewals needed for home purchases and remove those veterans’ protections. Another extension is the likely outcome under every result. Members in both parties have constituents depending on these programs, and neither side gains much by forcing an interruption.

Health, dairy and export financing, December 31. The February health law funds community health centers, the National Health Service Corps, diabetes programs and Temporary Assistance for Needy Families through December 31, although unspent balances mean services do not all stop January 1. The farm extension suspends older dairy law through the same date; reversion would require federal milk purchases intended to raise prices. The Export-Import Bank’s authority for new business also ends, though existing obligations continue.

Continuity extensions are likelier than overhauls for all three. A Democratic sweep gives Democrats reason to take short extensions now and pursue longer health funding in January. Farm-state members in both parties want to avoid the milk-price disruption. The administration and bipartisan Senate sponsors want the bank renewed, and Democratic gains would give Democrats leverage over a longer term.

Medicare payments. Extra hospital support for qualifying low-volume and Medicare-dependent hospitals, a pause in certain lab payment cuts and the temporary physician payment increase end with 2026. Lapses change provider payments, not Medicare coverage. No result leaves time to build a new payment system, so expect a bridge.

Defense authorization. The annual bill sets military policy, including procurement and personnel. The established annual cycle makes it one of the likelier year-end bills. Missing December delays new policies without shutting down the military. Republican losses add urgency to settle terms before committee control changes.

Nominations. The Senate has pending executive and judicial nominations, which generally return to the president when Congress ends. They become a top Republican priority if Democrats win the Senate, because the incoming majority could block Trump’s picks, and that is also when Democrats have the most reason to delay. If Republicans keep the Senate, there is far less need to finish every nomination in December.

Permitting. The September 30 bipartisan agreement would change energy and infrastructure approvals, protect existing permits and address data-center transmission costs. Nothing expires, but the negotiated bill dies when Congress ends. A scheduled November 9 Senate vote gives it a credible start, though House passage is less certain. Republican losses move it up their list, while a Democratic Senate would give Democrats room to renegotiate next year.

Farm bill and water projects. Senate Agriculture Chairman John Boozman (R-AR) wants a negotiated farm bill after the election, and the Water Resources Development Act would authorize port, navigation and flood-protection projects. Republican losses raise the urgency of both. Until negotiators show a two-chamber farm deal, another extension is likelier. The water bill, which brings projects home for members of both parties, has a reasonable chance of joining the year-end package.

Watch how quickly leaders settle the funding bill’s length and contents. A straightforward extension carrying transportation, flood insurance and other continuity measures, as September’s law did, signals that both sides want to avoid disruption. An early-2027 end date suggests the winners want the larger negotiations without a deadline looming.

A slow bill with disputed extensions left out signals a fight beyond spending, especially alongside repeated delays or threats to withhold votes. Missing provisions alone are not proof, since separate legislation may already be moving. As Thanksgiving and Christmas approach, floor time becomes leverage, and what leaders sacrifice to finish will show their real priorities.
