What a good idea. (I thought I'd post something positive amidst the gloom)
http://www.mydd.com/story/2006/9/28/155744/628"Trick-or-Vote® is the brainchild of one our most innovative political organizers, Jefferson Smith, founder of the Oregon Bus Project.
http://www.busproject.org It's a simple idea: "What's the one day you expect people to knock on your door?" Smith asks. Answer: "Halloween...which occurs just days before every November election."That makes it the perfect day for political canvassing. The Oregon Bus Project has been sponsoring "Trick-or-Vote"® since 2002. It's now one of the centerpieces of their GOTV campaigns. On Halloween weekend in Portland, Oregon, more than 800 canvassers will dress up in costumes and go door to door to hand out election info...along with a piece of penny candy (Smith calls it "Reverse trick-or-treating.") "We always give out something--a Tootsie Roll, a balloon, a piece of candy--with our campaign literature." he explains."
Not so great in Manhattan but should work elsewhere.
