My doctor, as it turns out, is a Republican. And not just any Republican. He is, it appears, one of the GOP's go-to guys in their war against the Affordable Care Act. He has testified before Congress, written several op-eds for prominent conservative publications and blogs, and is a frequent guest on right-wing radio. This guy is no lightweight. I felt a sinking feeling in my gut, and the more I read, the worse that feeling became.
