Question: how many times has the vice president been elected president?
Answer: In this capacity, four vice presidents have been able to announce their own election to the presidency: John Adams, Thomas Jefferson, Martin Van Buren, and George H. W. Bush. Conversely, John C. Breckinridge, in 1861, Richard Nixon, in 1961, and Al Gore, in 2001, all had to announce their opponent's election.
