With four front-runners over the age of 70, one heart attack suffered by candidate Bernie Sanders on the campaign trail and basically everyone younger than 70 having dropped out of the race, the presidential primaries for 2020 have been putting presidents’ ages on the agenda. President Trump, who is running for re-election, is himself the oldest president ever to be inaugurated (he was 70 at the time), and all four democratic frontrunners (Warren, Biden, Sanders, Bloomberg) would break that record still.
But taking a look at all presidents’ ages at the time of their inauguration since 1789, the trend only extends to the five individuals already mentioned. Before Trump and the 2020 line-up, presidents’ ages were actually below average. Barack Obama took office at 47 years and 169 days, according to Potus.com, making him the fifth youngest president at the time of inauguration. Bill Clinton, who was 46 when he took over, was the third youngest.
Some of the oldest presidents hail from past centuries. William Henry Harrison was 68 at his inauguration in 1841 (he died a month later of typhoid and pneumonia), making him the third-oldest president ever. James Buchanan, who took office in 1857, was the fourth-oldest president at 65.
