Who was the oldest Presidential candidate?

Peter Cooper (b. February 12, 1791) was the candidate of the Greenback party in 1876, when he was 85 years old.

Among the 2 biggest parties:

* In 1984 President Ronald Reagan became the oldest US presidential candidate, when he successfully ran for re-election. He turned 73 that February. * In 1996 Senator Bob Dole became the oldest US presidential candidate to run for a first term. He turned 73 that July. * Senator John McCain is 72, and is therefore not the oldest candidate. He would however be the oldest person sworn in as a new president, if he is elected. If he serves two terms, he will be the oldest president.
