Dana Milbank’s column in the Washington Post today asks Mitt Romney to prove once and for all that he is not a unicorn. Apparently 18,000 people have submitted a petition to the Arizona secretary of state to certify that Romney is not a unicorn before allowing his name to be put on the ballot. You can read all about it at mittromneyisaunicorn.com. There seems to be some equine confusion here. Romney couldn’t possibly be a unicorn, because every time he opens his mouth he proves himself to be a perfect ass. This would not likely disqualify him for the presidency, since there are precedents as recently as W. One suggestion was that Romney’s head be shaved to be sure there isn’t a horn under all that hair. Actually if you shaved his head, you would mostly likely find nothing.
