There was no Presidential election in 1950.

Five parties nominated candidates for the 2008 U.S. Presidential election, the Republican Party, the Democratic Party, the Libertarian Party, the Green Party and the Constitution Party. In addition to their candidates, Ralph Nader ran as an Independent.

That has always been false; there was not a U. S. Presidential election in 2002. The most recent U. S. Presidential election before 2012 was in 2008.
