Arnold Kling takes note of this, and concludes with this:
Wilkinson, once with the libertarian Cato Institute, now comes across as a full-fledged partisan Progressive Democrat. In theory, he could argue for his new views from a perspective that respects the ideas he no longer finds congenial. Instead, he has adopted a Krugman-esque approach of painting non-Progressives as cartoon villains. I don’t begrudge him his ideological evolution. But I do fault the manner in which he expresses it.
I’ve been onto Wilkinson for a long time; see, for example:
Pseudo-Libertarian Sophistry vs. True Libertarianism
Human Nature, Liberty, and Rationalism
Why Stop at the Death Penalty?
And I do begrudge his ideological evolution. Though it is more accurate to say (as I argue in some of the posts linked above) that Wilkinson wasn’t really a libertarian, even when he masqueraded as one. The mask is finally off.
