Majority margin is required to elevate a presidential nominee to a seat on the court.
A simple majority of 51 is all that is required for a president's nominee to gain a seat on any federal court, including the Supreme Court. If the vote is deadlocked at 50-50, the vice president casts the deciding vote. There are no explicit requirements in the U.S. Constitution for a person to be nominated to become a Supreme Court justice. No age, education, job experience, or citizenship rules exist. In fact, according to the Constitution, a Supreme Court justice does not need to even have a law degree. An absolute majority is necessary to prevail in the presidential and the vice presidential elections, that is, half the total plus one electoral votes are required. With 538 Electors, a candidate must receive at least 270 votes to be elected to the office of President or Vice President.
