Conservatives like to say that their position is all about economic freedom, and hence making government’s role in general, and government spending in particular, as small as possible. And no doubt there are individual conservatives who really have such idealistic motives.

When it comes to conservatives with actual power, however, there’s an alternative, more cynical view of their motivations — namely, that it’s all about comforting the comfortable and afflicting the afflicted, about giving more to those who already have a lot. And if you want a strong piece of evidence in favor of that cynical view, look at the current state of play over Medicaid.

Some background: Medicaid, which provides health insurance to lower-income Americans, is a highly successful program that’s about to get bigger, because an expansion of Medicaid is one key piece of the Affordable Care Act, a k a Obamacare.

There is, however, a catch. Last year’s Supreme Court decision upholding Obamacare also opened a loophole that lets states turn down the Medicaid expansion if they choose. And there has been a lot of tough talk from Republican governors about standing firm against the terrible, tyrannical notion of helping the uninsured.
