Final answer:
The Senate must have 51 votes for a candidate to win the Vice Presidency.
Step-by-step explanation:
In the event that the Senate must choose a Vice President, it would take 51 votes for a candidate to win. This is because the Senate is made up of 100 senators, and a majority vote is needed to make a decision. Since 51 is more than half of 100, it is the minimum number of votes needed for a candidate to win.
