Want to Keep Healthy on the Campaign Trail? Good Luck

For veterans of the presidential campaign trail, getting sick is just part of the candidate's job description.

So while Hillary Clinton's bout with pneumonia and faintness at a Sept. 11 memorial service has set off more speculation about her overall health, old campaign hands don't seem nearly as fazed.

“Candidates, like most in high stress/high travel jobs, are constantly dealing with annoying coughs, colds, whatever,” Stuart Stevens, Mitt Romney's campaign manager in 2012, told STAT in an email. “It's hard to take a day or two off and rest and that just makes it worse. It just happens. To everybody.”
