While it’s sometimes said that politics can be a full-contact sport, some campaign risks have never been more obvious than during recent presidential primary races.

One former candidate, Carly Fiorina, fell off the stage at an Indiana rally, while another, Ben Carson, lost a tooth at a breakfast event in South Carolina. In a tragic example, a Carson campaign worker died from injuries sustained in a car accident. These events may be indicative of physical hazards also faced by voters, conference attendees, volunteers and journalists on the campaign trail.
