In his op-ed column today, David Brooks absolutely nails the angriest dwarf to the wall: The Mysterious Stranger.

The newly liberated Dean doesn’t worry about having a coherent political philosophy. There is a parlor game among Washington pundits called How Liberal Is Howard Dean? One group pores over his speeches, picks out the things no liberal could say and argues that he’s actually a centrist. Another group picks out the things no centrist could say and argues that he’s quite liberal.

But the liberated Dean is beyond categories like liberal and centrist because he is beyond coherence. He’ll make a string of outspoken comments over a period of weeks — on “re-regulating” the economy or gay marriage — but none of them have any relation to the others. When you actually try to pin him down on a policy, you often find there is nothing there.

For example, asked how we should proceed in Iraq, he says hawkishly, “We can’t pull out responsibly.” Then on another occasion he says dovishly, “Our troops need to come home,” and explains, fantastically, that we need to recruit 110,000 foreign troops to take the place of our reserves. Then he says we should not be spending billions more dollars there. Then he says again that we have to stay and finish the job.

At each moment, he appears outspoken, blunt and honest. But over time he is incoherent and contradictory.

He is, in short, a man unrooted. This gives him an amazing freshness and an exhilarating freedom.
