What to Expect: How Democrats Will Exercise Power in the 120th Congress

With the dust settling after the 2026 midterm elections, the political landscape in Washington is set for a dramatic shift. As the 120th session of Congress prepares to convene in January 2027, Democrats are poised to take control of Capitol Hill.

However, wielding legislative power in a divided government comes with distinct structural limits. With Republican President Donald Trump holding veto power and Democrats lacking a 60-vote filibuster-proof majority in the Senate, sweeping legislative overhauls are largely off the table.

Instead of major statutory overhauls, expect House and Senate Democrats to focus on a three-part strategy: aggressive executive branch oversight, targeted messaging legislation on cost-of-living issues, and strategic use of procedural leverage.

Here is a breakdown of what Democrats are reasonably expected to do once the new session begins.

1. Unleashing Aggressive Oversight and Subpoena Power

The most immediate shift will take place in hearing rooms across Capitol Hill. Controlling committee gavels in both chambers empowers Democrats to issue subpoenas, hold public hearings, and set the investigative agenda.

• Executive Branch & Cabinet Scrutiny: Key panels—such as the House Oversight Committee (under expected Leadership by Rep. Robert Garcia) and Senate Finance (under Sen. Ron Wyden)—will launch deep investigations into executive branch ethics, spending allocations, and potential conflicts of interest.

• Foreign Policy and Defense: Expect high-profile hearings scrutinizing executive-led foreign policy actions, international trade maneuvers, and military operations in key conflict zones like the Middle East.

• Impeachment Pressures: While Democratic leadership under expected House Speaker Hakeem Jeffries will carefully weigh the political risks, progressive members will press committee chairs to open formal impeachment inquiries into administration officials or the President.

2. A "First 100 Days" Agenda Focused on Affordability

Democratic leaders plan a swift rollout of high-visibility legislative packages designed to highlight economic contrast.

• Cost-of-Living & Healthcare: Priority bills will focus on restoring expanded Affordable Care Act subsidies, reversing recent Medicaid rollbacks, and addressing core affordability pressures in housing and groceries.

• Energy and Consumer Protection: Expect targeted measures aimed at utility costs, corporate pricing transparency, and data center energy consumption.

The Reality Check: While these bills are expected to pass the House, most will hit a wall against the Senate filibuster or a presidential veto. The primary goal of this agenda is strategic—establishing a sharp contrast with the White House ahead of the 2028 election cycle.

3. Reclaiming Control of the Senate Confirmation Pipeline

Holding a Senate majority provides Democrats with a powerful tool that does not depend on presidential approval: the power of confirmation.

• Judicial Nominees: The Senate will effectively halt the confirmation of conservative judicial nominees, creating a stall in the federal judiciary.

• Executive Appointments: High-level executive appointments and agency vacancies will face rigorous scrutiny, forcing the White House to negotiate or leave key posts unfilled.

4. High-Stakes Fiscal & War Powers Battles

Because the federal government requires Congressional approval to spend money and borrow, Democrats will utilize statutory deadlines to push their priorities.

• Budget & Debt Ceiling Leverages: Expect sharp standoffs over upcoming debt ceiling deadlines and annual funding bills as Democrats push to attach policy riders that limit executive authority and protect domestic discretionary spending.

• War Powers Resolutions: Democrats, likely joining with some libertarian-leaning Republicans, will attempt to force floor votes on War Powers Resolutions aimed at curtailing unauthorized executive military operations.

The Bottom Line

The 120th Congress will not be defined by major bipartisan landmark bills, but by intense checks and balances. By combining committee oversight, targeted messaging legislation, and strict confirmation control, Congressional Democrats aim to reshape the political narrative heading into the next presidential cycle.
