Theodore Roosevelt was the youngest, at 42 years and 322 days. The next one will be a fair bit older, whatever happens. Donald Trump celebrated his 70th birthday on 14 June.

Hillary Clinton, meanwhile, turns 69 some two weeks before the election, and would become the second-oldest president on inauguration.
