What are the chances that the next president will die in office? Based on what the nominee’s opponents have been saying, the odds seem fairly high. Donald Trump has spent recent weeks claiming that Hillary Clinton doesn’t have the “mental and physical stamina” necessary to fulfill the role of president. Clinton and her surrogates, meanwhile, responded by calling on Trump to release his health records and then, when he did, attacked the doctor who vouched for Trump’s health as a quack.
