Some presidential candidates didn't survive their scandals. In 1987, the Miami Herald reported that White House hopeful Gary Hart, a former Democratic Colorado senator, was having an affair with a young model. Hart challenged the media to prove the allegations. Soon after, the National Enquirer obtained photographs of a model named Donna Rice sitting on Hart's lap on a yacht named Monkey Business. Once the pictures were published, Hart dropped out of the race. Hulton Archive/Getty Images
Democratic presidential nominee Sen. George McGovern, right, chose Sen. Thomas Eagleton, left, as his running mate in 1972. But when it was revealed that Eagleton had been hospitalized for depression where he underwent electroshock therapy, the scandal was enough to force him off the ticket. He was replaced by a Kennedy in-law and former director of the Peace Corps, Sargent Shriver. McGovern lost in a landslide to Republican incumbent Richard Nixon.
When Nixon was running as Dwight Eisenhower's Republican vice presidential nominee in 1952, a scandal over a dog nearly got him thrown off the ticket. Nixon was accused of accepting inappropriate campaign funds. A supporter also gave Nixon a pet cocker spaniel, which the family had named Checkers. Nixon went on TV and delivered an emotional speech defending himself. In a stroke of political wizardry, the speech included Checkers. "... the kids, like all kids, love the dog and I just want to say this right now, that regardless of what they say about it, we're gonna keep it," he said. The speech worked. Eisenhower kept Nixon on the ticket, and they won election to the White House six weeks later. Hulton Archive/Getty Images

Long before he ran for President, Andrew Jackson married his wife, Rachel, in 1791. Later they discovered that her previous husband had not gotten a proper divorce. After they fixed it, the Jacksons quietly remarried in 1794. During the 1828 election campaign, Jackson's opponents spread rumors that he'd slept with Rachel while she was married to another man. Although words such as "adultery" and "bigamy" were thrown around like bombs, Jackson still managed to win the election. Kean Collection/Getty Images/MPI/Getty Images)
