An unexpected group of Americans at high risk for HIV and hepatitis C turn out to be Trump supporters who are mostly straight, white, rural and poor. Here’s why. Last year, hoping to prevent a sudden outbreak like the 2015 incident in Indiana, the Centers for Disease Control and Prevention listed the 220 counties most vulnerable to similar outbreaks fueled by the injection drug use of opioids. It just so happens that 56 percent of them are located in Kentucky, Tennessee and West Virginia, with clusters in Arizona, Utah, Missouri, Michigan, Maine, Montana, California and other states. Looking at the voting records of those counties, news site Vocativ discovered that 98 percent of those 220 counties supported the Trump ticket.
