The Constitution gives the Senate a power the House does not share. The president “shall nominate, and by and with the Advice and Consent of the Senate, shall appoint” ambassadors, Supreme Court justices and other officers of the United States. In practice, that covers all federal judges, cabinet secretaries, many agency officials, U.S. attorneys and marshals, and military promotions.
Because confirmations now need only a simple majority to advance, the party that controls the Senate largely controls the confirmation process. This explainer describes how that works, in terms that apply whichever party holds the chamber after November 3.
- Under Article II, the president nominates and the Senate confirms judges and senior officials; the House has no role.
- Since 2013 (most nominations) and 2017 (Supreme Court), cloture on nominations needs only a simple majority.
- The majority controls committee chairs and the floor schedule, which decides which nominees get hearings and votes, and when.
- A Senate controlled by the president’s party can confirm at a steady pace; one controlled by the other party can slow or stop nominations.
- A new Senate convenes Jan. 3, 2027; the outgoing Senate can keep confirming nominees until then.
How a nomination becomes a confirmation
- Nomination. The president sends the nomination to the Senate.
- Committee. It is referred to the committee with jurisdiction: Judiciary for judges, U.S. attorneys and marshals; Foreign Relations for ambassadors; Armed Services for military promotions; and so on. The committee holds hearings and votes on whether to report the nominee to the full Senate.
- Floor. The majority leader decides when to bring a nomination up. If senators will not agree to a vote by unanimous consent, the leader files cloture to end debate.
- Confirmation vote. A simple majority of senators voting confirms. The vice president can break a tie.
Why the majority matters so much now
For most of the Senate’s modern history, ending debate on a nomination took a supermajority, which gave the minority party leverage. That changed in two steps:
- Nov. 21, 2013The Senate set a precedent that cloture on nominations, other than to the Supreme Court, requires only a majority.
- Apr. 6, 2017The Senate extended the majority threshold to Supreme Court nominations, ahead of Neil Gorsuch’s confirmation.
- Apr. 3, 2019Post-cloture debate on most nominations was cut to two hours, excluding Supreme Court, circuit court and cabinet-level nominations.
Majority leaders of both parties have changed the rules further when frustrated by delays, and the minority has called each change an abuse. The cumulative effect is simple: a united majority can confirm nominees over the minority’s objection. We explain the mechanics in the nuclear option, explained and what the filibuster is.
What the majority controls
Committee gavels
Majority partyCommittee chairs decide when to hold hearings and votes. The majority also holds more seats on each committee, so it can report nominees to the floor without minority support.
The floor calendar
Majority leaderFloor time is the Senate’s scarcest resource. The majority leader chooses whether to spend it on nominations or legislation, and which nominations go first.
Senators also retain some individual tools. The “blue slip” tradition, under which the Judiciary Committee chair seeks home-state senators’ views on certain nominees, has been applied differently over time and is set by the chair rather than by rule. Any senator can refuse unanimous consent and force the majority to spend floor time on cloture votes, which can slow, but not ultimately stop, a determined majority.
Two scenarios for 2027
| President’s party holds the Senate | Other party holds the Senate | |
|---|---|---|
| Judicial nominees | Hearings and floor votes proceed on the majority’s schedule | Chair controls whether and when hearings occur; nominees can stall |
| Cabinet and agency picks | Confirmed with party-line votes if needed | Nominees must win over some majority senators, or wait |
| Supreme Court vacancy | Majority can confirm without minority votes | Majority can decline to act, as the Senate did in 2016 |
| Recess appointments | Less needed | Possible only if the Senate takes a qualifying recess |
The Constitution’s Recess Appointments Clause lets the president fill vacancies “that may happen during the Recess of the Senate,” with commissions that expire at the end of the Senate’s next session. In practice, the Senate has long used brief pro forma sessions to avoid triggering it.
The lame-duck window
The current Senate keeps its full power until the new Congress is sworn in at noon on January 3, 2027. Nominations not confirmed by the end of a session are generally returned to the president under Senate rules unless senators agree otherwise, so there is pressure to finish pending confirmations before the year ends. That is one reason December is often busy, as we describe in the lame-duck session explainer.
The Senate math behind it
Republicans hold 53 seats and Democrats 47, including two independents who caucus with them. Democrats need a net gain of four for a majority, because Vice President JD Vance breaks ties. Our Senate Toss-Up rundown covers the races that decide it, and what the midterms mean for the Supreme Court looks at the judicial stakes in more depth.
Frequently asked questions
Does the House vote on judges or cabinet nominees?
No. Under Article II of the Constitution, the president nominates and the Senate alone provides advice and consent. A House majority has no role in confirmations.
How many votes does it take to confirm a federal judge?
A simple majority of senators voting. Since 2013 for most nominations and 2017 for the Supreme Court, cloture on nominations also requires only a majority.
What does the Senate majority control in confirmations?
Committee chairs and majorities, which control hearings and committee votes, and the floor calendar, which the majority leader uses to decide which nominations get votes and when.
Can the minority party block a nominee?
It can slow nominees by refusing unanimous consent and forcing cloture votes, but a united majority can still confirm. The minority cannot block a nominee on its own.
When does the new Senate take over?
At noon on Jan. 3, 2027, when the 120th Congress convenes. The outgoing Senate retains full power until then.
Senate control is the single biggest factor in how many of a president’s nominees are confirmed and how quickly. Whichever party holds 51 seats in January 2027 will set the pace for judges and appointees for the next two years.
