What is the vote requirement for passage in the Senate?
It takes unanimous consent to agree to take the vote, and if unanimity doesn't exist (if there is one objector), then it takes 60 to get around the objection and set a time to take the vote.
Waiving a statutory point of order takes 60 votes. E.g., the bill is off budget.
Passage is a majority of those voting.
It is not uncommon for the senate to agree to combine one of the inevitable 60 vote hurdles with a vote on final passage, and just agree that it takes 60 votes to obtain final passage. IOW, take one vote at a 60 hurdle, instead of one at 60 and one at majority.
Passage of treaties takes 2/3rds, per the constitution.
