More than one political scientist has observed that American voters often vote for candidates who work against the voters' economic interests.
Jonathan Metzl is a physician, and comes at the issue from another angle: he says voters' decisions can actually shorten their lives. He gives examples of policies implemented by anti-government politicians, like denying Medicaid expansions, cuts to social services, and looser gun restrictions.
These are among the cases Dr. Metzl cites in his book Dying of Whiteness: How the Politics of Racial Resentment Is Killing America's Heartland. He makes the case that the results of voting can shorten peoples' life spans.
