Top 10 Dumb Mistakes in U.S. Presidential Elections
These are either mistakes that incumbents and challengers made which cost them the election. This list is generally more focused on gaffes and campaigning mistakes rather than policy mistakes.(Also, this list is for the general elections - not the primaries)
This was an election Dewey was expected to win easily, but he didn't. Truman, the incumbent, was supposedly unpopular, but he gained support from working-class Americans through vigorous campaigns across the country. Dewey stuck to vague platitudes and couldn't energize voters.
Perot was the most successful Independent candidate in American history with high poll numbers. However, at one point, he dropped out of the race, citing a threat against his family. When he re-entered the race, he lost most of his momentum. His decision to drop out and re-enter made him look indecisive.
He never had a chance of being anything more than a spoiler.
At a disadvantage, McCain took a creative risk by choosing a woman who was youthful, energetic, and diversified the ticket. However, her very conservative views, numerous gaffes, and anti-intellectualism turned Independent voters away.
Goldwater held firm conservative and libertarian principles and wouldn't make an effort to relate to a broader audience. His comments about using nuclear weapons in Vietnam allowed him to be portrayed as unstable. He didn't even try to reach out to more moderate members of his party or the public at large.
Theodore Roosevelt felt that Taft had rolled back many of his progressive policies. While this perception is not entirely accurate, Taft lacked the diplomacy and rhetoric to work out a compromise with Roosevelt or convince Progressive voters to come to his side, resulting in a split ticket.
Carter spent much of his time talking about environmentalism, humanitarianism, gender equality, and anti-nuclear proliferation. However, these were not the main concerns of millions of frustrated working-class voters. Carter's opponent, Reagan, focused on jobs, strength, and productivity at every opportunity.
Al Gore didn't want Bill Clinton to heavily campaign with him because he feared the sex scandal would hurt him. However, Clinton was still a very popular president in a booming economy. In a very tight election, this could have made a significant difference.
The first televised presidential debate was historic. Kennedy appeared healthy and confident, while Nixon appeared irritated and lethargic. Though radio listeners appreciated Nixon's performance, television viewers overwhelmingly preferred Kennedy. There were other debates, but most people tuned out after the first one.
1992 was a year of economic stress and high crime rates. While Bill Clinton offered a gentle charisma and showed adeptness in relating to struggling people, George H.W. Bush allowed himself to be portrayed as rich and aloof. Bush never cared for the grandiosity of political rhetoric, but voters did. Clinton won because he seemed more relatable and hungry for change.
Robert Kennedy was doing well as an anti-war candidate before his assassination. Humphrey's moderate support for the Vietnam War alienated many Democrats. He was unable to distinguish himself from his opponent, Nixon, or the unpopular incumbent, Johnson.
