In the Washington Post, Michael Gerson argues the thing that might cost Hillary Clinton the election is something that neither presidential candidate is spending much time talking about: Obamacare. He writes that immigration may be “the main motivating issue” that gets voters to turn out, but “the general atmosphere of contempt for government that helps Trump—of disdain for the weakness and incompetence of the political class—is due to the Affordable Care Act.” Gerson adds, “A higher proportion of Americans [19 percent to 18 percent] believe the federal government was behind the 9/11 attacks than believe it has helped them through Obamacare.”

Gerson is hardly a conservative firebrand or a Tea Partier. (If he were, he wouldn’t call Obamacare—officially the Patient Protection and Affordable Care Act—the “Affordable Care Act.”) So if Gerson can see how toxic Obamacare is for Democrats, one wonders why more Republican candidates can’t seem to see that as well.
