The Senate can defeat a bill with 51 votes.
2/3 of Senate
Well, to overrule a veto: 2/3
The members of the House and the Senate.
If all members vote, 51 votes are needed to pass a bill. Otherwise it passes if more than half of the votes are "Ayes".
A simple majority ( 51 votes if all vote) will pass any bill in the Senate. (Please note that all tax bills must originate in the House.)
Actually, there are a limited amount of people in the Senate. Anyway, the bill is passed when there are more votes to pass the bill EX: 60 wants bill, 25 doesn't
The bill after every Senate and Delegate has approved or the votes win, the bill then must go to the executive branch.
In the U.S. Senate, 51 votes are needed to pass a bill on the floor. A bill can also pass on a tie vote (50 - 50 or otherwise), as the Vice President will then cast a vote to break the tie. A bill cannot even reach the floor for a vote, however, if it is the subject of a filibuster unless there are 60 votes for cloture (which will allow a floor vote on the bill). In the U.S. House, 218 votes are needed to pass a bill on the floor.
A simple majority is all is needed . This means 51 votes if all the senators vote . 50 votes will suffice if the vice-president will vote in favor of the bill. However, in order to shut down debate and bring a controversial bill to a vote, that, to end a filibuster, requires a 60% vote in favor or 60 votes if all the senators vote.
when the president vetoes a bill, a 2/3 vote is required where 2/3 or higher senators vote for the bill to become a law.
3/4 votes from the state legislature, house of representatives and senate
it gets introduced then sent to committees (house of reps) then house votes on it then introduced to senate sent to senate committees senate votes on it voting is called floor action because the bill is on the "floor" for voting then to president where he approves or vetoes
