If Donald Trump wins a second term, he will enter the White House at 78 years old, making him the oldest person ever elected president. Anything can happen over four years, and there is, of course, a chance he will not complete his term. The former president, who has already been the subject of two impeachment efforts, has refused to release even basic information about his health. Given that state of affairs, it seems important to have a sense of how his vice president might govern if elevated to the top job.
