Lefty Halloween Costume Ideas Needed

This diary is short and sweet.  I need the help of the Dkos community to come up with some great Halloween costume ides that are topical and left-leaning.  My neighborhood is filled of Bushies, or at least uber-conservatives, and I need something to dress up as so when they bring their kids to our house for candy, the conversation goes something like this:

Them: "Happy Halloween!  Great costume... what are you?"

Me: "Isn't it obvious?  I'm [insert your great costume idea here]."

Them: (Nervous laugther) "Ah.  Um.... well... Have a good night."

Me: "Good luck with your failed policies and small mind!"

So... any ideas?
