The April Kaiser Health Tracking Poll examines the role of health care issues in the presidential election. Health care is one of the top four issues mentioned by voters when asked which issues they most want to hear candidates discuss in the campaign, but half as many cite health care as mention the economy and jobs. It also examines the public’s experiences with prescription painkiller abuse and access to mental health care, as well as their views on efforts to combat painkiller and heroin addiction. It also asks about confidence in the safety of the drinking water supply in the wake of the lead contamination crisis in Flint, Mich., and their views of the government’s performance.
