Some conservatives have urged young uninsured Americans to steer clear of the Affordable Care Act’s health insurance exchanges, and Sen. Angus King (I-ME) thinks that’s reprehensible.

“That’s a scandal — those people are guilty of murder in my opinion,” King told Salon on Friday. “Some of those people they persuade are going to end up dying because they don’t have health insurance. For people who do that to other people in the name of some obscure political ideology is one of the grossest violations of our humanity I can think of. This absolutely drives me crazy.”

With the exchanges set to open Tuesday, there has been an emerging effort on the right to persuade young people not to enroll in what is a thinly veiled effort to undermine the law.

A web video released earlier this month by Generation Opportunity, a group with ties to GOP benefactors Charles and David Koch, featured a disquieting scene involving someone in an Uncle Sam mask performing a procedure on a young woman.
