How many votes must a cardinal get before he is elected pope?

Answer 1

To elect the Pope is required a majority of 2/3 of the cardinal electors.. After the 33th vote without success the two cardinals who have received the most votes will enter a runoff electionc. Even in this case we will require a majority of 2/3. The two cardinals remained will not actively participate in the vote. The requirements for becoming Pope, officially, are three: male, baptized, not married.

Answer 2

It is required that someone receive a super-majority of 2/3+1 to be elected bishop of Rome. (The electors are cardinals, but the candidate can be anyone they choose, assuming he is a fully initiated Catholic and of age).

As of March 2015, there are 125 cardinal electors. 84 votes would be required to elect a pope.

Answer 3

2/3 plus one of the cardinals present for the conclave must vote for the person.
