/* Presidential dominance */ 5,000 votes in Ohio
John F. Kennedy (the next Democratic non-incumbent to win the White House) won the 1960 election as the result of voter fraud in Chicago (and several other locations), with a mere 0.2% difference in the popular vote.
It took the aftermath of the Watergate scandal to get the next, non-incumbent Democrat elected in 1976 in a very close election in which Democrat Jimmy Carter received 50.1% of the popular vote to Gerald Ford's 48.0%. 5,000 popular votes in the State of Ohio would have made the difference.
The next non-incumbent Democrat victory occured in 1992, in which third party candidate H. Ross Perot took away 19% of the popular vote from the Republican candidate, incumbent George H.W. Bush. And even though Bill Clinton was twice elected, he never once had a majority of the vote (43.0% in 1992; 49.2% in 1996). More people (the majority of voters) voted against Clinton for President than ever voted for him.
