But it is exactly like the nomination of Clarence Thomas to the Supreme Court. That is, an unbelievably obvious but potentially effective attempt to jiu-jitsu the standard identity politics of the moment in a way that flummoxes the Democrats. I would spell out the logic but I think it's obvious and am at a computer for only sixty seconds.

The image to have in mind is not Dan Quayle: a person with quite a bit of grounding in national issues who was added to the ticket in an attempt to jazz it up. Always and only the comparison should be with Clarence Thomas -- with this one interesting difference. Thomas was a shrewd choice not simply because his race made it more complicated for Democrats to oppose him but also because, once confirmed, all evidence suggested to conservatives that he'd be the kind of Justice they were looking for. In Palin's case, this seems to be a choice that looks forward to Election Day, and not one day beyond that.
