Libertarians for Obama

Is the theme of a new series of posts on Marginal Revolution. The point, obviously, is that it's been a long time since the idea that the Republicans are the party of free markets (or indeed free anything) has become a sick joke, and it'd be better to defect for Obama, who at least looks like he might do better on civil liberties:

Have libertarians gained on other margins in the past eight years? Not at all. Under the Republicans we have been sailing due South-West on the Nolan Chart – fewer civil liberties and more government, including the largest new government program in a generation, the Medicare prescription drug plan, and the biggest nationalization since the Great Depression. Tax cuts, the summum bonum of Republican economic policy, are a sham. The only way to cut taxes is to cut spending and that has not happened.

While I don't actually disagree with anything that's said there, I still find myself slightly surprised that anyone actually feels the need to make this argument. Libertarians always like to pose as the party for the high IQ set - how come they're only just figuring all this out now?
