[Ed. – The Constitution specifies when prospective candidates are too young to run and serve, but should it designate who is told old?]
Should he win reelection and complete his full second term, President Trump will surpass Ronald Reagan as the oldest person to ever hold the office. But Trump’s age is hardly ever talked about, because leading Democrats Joe Biden and Bernie Sanders would be older than Reagan at the start of their presidencies.
As medical science improves and life expectancy increases, more and more candidates may be willing to test the limits of age. And there’s nothing in the law that prevents them from running and winning. While one could argue that it should ultimately be up to the voters to decide whether somebody is fit to serve, there are clear issues with this test.
…[T]here’s a lack of objective information available for voters to determine whether somebody is physically and mentally unfit to serve out a term in office. Candidates are not required to submit medical information, and both Trump (with his ridiculous doctor’s note) and Hillary Clinton (with her pneumonia cover-up) were opaque about their health in 2016.
