How many times has the Vice President been chosen by the U.S. Senate?
Once. In the Presidential election of 1836, the election for Vice President was decided in the Senate. Martin Van Buren’s running mate, Richard M. Johnson, fell one vote short of a majority in the Electoral College. Vice Presidential candidates Francis Granger and Johnson had a “run-off” in the Senate under the 12th Amendment, where Johnson was elected 33 votes to 17.
