In sicker communities, Trump got more votes. Is that why he won?

The worse a community’s health the more strongly its voters backed Donald Trump in the 2016 election compared to their support for Mitt Romney, the 2012 Republican presidential nominee, researchers reported on Monday.

The findings suggest that public health “might influence” how people vote, said Dr. Jason Wasfy of Massachusetts General Hospital, who led the study, which looked at factors such as death rates, diabetes prevalence, and teen pregnancy. “The communities that shifted from Romney to Trump in general have worse public health.”
