two-thirds majority
Veto-proof voting margin
A two-thirds majority is a supermajority requiring at least two-thirds of votes cast to pass a measure—67 out of 100 votes, for instance.
Many legislatures require a two-thirds majority for constitutional amendments, treaty ratifications, or overriding vetoes: The Senate needs a two-thirds majority to convict in an impeachment trial.
The threshold ensures broad consensus for weighty decisions.
