First Mitt Romney used his wife to justify some pretty nasty attacks on President Obama.

Now Mitt Romney is using his wife to explain away why Mitt used to strap his dog to the roof of the car during family vacations.

So Mrs. Romney is now a full-fledged campaign spokesman, dealing with unemployment policy and crisis communications.

But please don’t say anything about Romney spokesman Ann Romney’s credibility, accuracy, or knowledge, because that would be sexist.

No. What’s sexist is using your wife as a political human shield because you’re unable, unwilling, or simply afraid to run for president on your own two feet.

PS Someone should ask Romney campaign spokesman Ann Romney if she thinks stay at home moms are lacking in dignity.
