Meh. I know y'all think it's hilarious, but I don't think it's very professional. He's stooping to their level, and I personally don't find it attractive. People get up in arms when McCain or Palin criticize Obama and say rude things, but when Obama says something about Sarah Palin that simply isn't true by virtue of her being a VP candidate, everyone smirks and laughs. All presidential and VP candidates are apprised on issues regarding homeland security during the election as they get closer to the finish line, that way they can — hopefully — make promises they can actually keep. Sarah Palin probably knows more about nuclear issues than most of us, regardless of whether or not she can articulate them.
I await the angry responses, flaming torches and pointy pitchforks.
