A Senate supermajority is not one number. It is two, and they do very different jobs. Sixty votes lets the Senate move a bill past a filibuster. Sixty seven votes, along with 290 in the House, is what it takes to override a veto.
The 60 vote rule is about the filibuster. In the Senate, most bills cannot get a final vote until debate officially ends, and any senator can drag that debate out. That stalling tactic is the filibuster. To shut it down, the Senate needs what is called a cloture vote, and cloture takes 60 votes. So when you hear that a party has a “filibuster proof” Senate supermajority, it means the party can push legislation past those delays without help from the other side.
Clearing the filibuster only gets a bill out of the Senate, though. The House still has to pass the same bill, and then it goes to the White House. Trump can sign it, or he can veto it, which means he refuses to sign it and sends it back to Congress with his objections. A 60 seat Senate has no power to stop that.

The 67 vote rule is about the veto. The Constitution says Congress can override a veto only if two thirds of the Senate and two thirds of the House both vote to pass the bill again. If every senator votes, two thirds of 100 is 67. If every House member votes, two thirds of 435 is 290. Both chambers have to hit their number. If either one falls short, the veto stands and the bill dies.
Democrats hold 54 Senate seats and Republicans hold 44, with the races in Alaska and Mississippi still too close to call. If Democrats win both, they reach 56. To get to 67, they would need 11 Republican senators to vote with them. In the House, Democrats have won more than 250 seats, so they would also need roughly 30 or more House Republicans to cross over on the same bill.
Veto overrides are rare because they require a big chunk of the party that holds the White House to vote against its own leader. Trump has been on the losing end of one before. In his first term, he vetoed 10 bills, and Congress overrode just one: the annual defense bill in January 2021, when enough Republicans broke with him to keep military funding on track.
There are also ways around the 60 vote rule that need no Senate supermajority at all. A process called budget reconciliation lets the Senate pass certain tax and spending bills with a simple majority of 51. Nominees, including cabinet picks, federal judges and Supreme Court justices, also only need a simple majority after Senate rule changes in 2013 and 2017. And because the filibuster is a Senate rule and not part of the Constitution, a majority can vote to change it. The veto works differently. It is written into the Constitution, so no Senate rule change can lower the 67 vote bar, and even a bill passed through reconciliation can still be vetoed.
The newly elected Senate and House do not take office until January 3, 2027. Until then, the current Congress, where Republicans hold the Senate 53 to 47, keeps working through the lame duck session, the stretch between an election and the day the winners are sworn in.
A 56 seat Democratic majority would decide which bills come to the floor, who chairs committees, which investigations move forward and whether Trump’s nominees get confirmed. With a Democratic House alongside it, Democrats can send legislation straight to Trump’s desk and force him to either sign it or veto it in public.
What it cannot do on its own is take away Trump’s veto. That takes 67 votes in the Senate and 290 in the House, and right now neither party gets there without votes from the other side.
