On Nov 8, 2016, a tumultuous election cycle came to an end when Donald Trump was elected president. Trump's controversial election has since inspired a series of protests, most notably, the Women's March. Now, as of Nov. 2019, Trump's approval rating is 43%, according to a Gallup poll, an approval rating that falls significantly below that of America's recent presidents. 

It leads the question, what is President Trump's likelihood of reelection based on the failed reelections of past presidents? If the reelection slips, Trump will be the first president since George Bush Sr. to not secure a second term. Below is a list of the last five presidents who failed to win a second term and the reasons why they came up short.

George Bush, Sr.

President George H.W. Bush, the 41st U.S. president, is also known as Bush Sr. to differentiate him from his son George W. Bush, who won the presidency in 2000. His son ended up being re-elected and was followed by current President Obama. Bush Sr. served between 1989 and 1993, after being elected in the fall of 1988. Under his watch, the United States undertook its first invasion of Iraq. The mission was a resounding success, but a struggling U.S. economy was attributed to Bush's eventual unseating by President Bill Clinton, who ended up being elected for two terms.

Jimmy Carter

President Jimmy Carter was the 39th U.S. president and lost out to President Reagan, who went on to serve two terms. As with President Bush and many presidents that aren't re-elected, Carter served during a struggling U.S. economy that was suffering through high-interest rates and inflation. His foreign affairs track record was also described as uneven and included an unsuccessful hostage rescue exercise in Iran that began in Nov. 1979. Carter's foreign relation successes since he was president kept him in the public eye. Carter engaged in negotiations with North Korea in 1994, and the country agreed to freeze its nuclear weapon ambitions.

Gerald Ford

President Gerald Ford served right before President Carter as the 38th president of the United States. Ford was originally President Richard Nixon's vice president and was nominated as president after Nixon resigned his post following the Watergate scandal. Ford also failed to win re-election, which occurred back in 1976. Like Carter, he served during a period of difficult domestic economic circumstances that included stagflation, or minimal economic growth during a period of high inflation. The country also encountered energy shortages during his tenure. In 1974, Ford granted a pardon to Nixon, and this is a reason cited for his failure to win re-election.

Herbert Hoover

President Herbert Hoover was the 31st president and served between 1929 and 1933. The stock market crash of 1929 occurred right after Hoover entered office, and he also served through the Great Depression. Needless to say, his hopes of winning re-election after these events were going to be minimal. He was succeeded by Franklin D. Roosevelt, who ended up serving three terms.

William Taft

President William Taft served as the 27th president between 1909 and 1913. He was said not to enjoy serving as president, instead, having preferred to be a judge. He also struggled to succeed Roosevelt, who is considered one of the most popular presidents in the 20th century. In fact, his relationship as a closer friend to Roosevelt was reportedly a big factor in his election as president. His relationship with Roosevelt soured while Taft was in office, and this was thought to have minimized his chance of re-election.

The Bottom Line

Presidents that serve during times of turmoil, especially when it comes to a domestic recession or difficult economic environment, usually have a difficult time winning re-election. At other times, the presidents above were simply unable to make their marks on history and capture enough popularity to win a second term in office.
