Megan McArdle:

Sarah Palin is what the McCain camp has badly needed: an attack dog who can be deployed against Obama. She slides the stiletto in without either losing her femininity or coming across as catty, and given that she’s married to an eskimo, it’s going to be hard to fit her into the narrative of conservative closet racists trying to perpetuate white domination.

Now, wait a doggone minute here:

• Is Megan trying to say that all prejudices are created equal? Just because you’re not prejudiced against Eskimos means you’re altogether free from prejudice? Wait until the folks in Alabama hear about this!
• Does anybody look at blue-eyed Todd Palin and think, “Hey, Nanook, where’s your igloo?”

This whole identity-politics thing has gotten out of hand, when marrying “first dude” Todd Palin is considered an act of tolerance.
