I've been registering people individually (at my church) and w/ my chapter's efforts for several weeks. Saturday I set up at a car show and later at afternoon pee-wee football (these are great places, you get parents, grandparents, aunts, uncles, etc...).
I'm impressed with the "intensity." People seem really hype to do this. Once registration closes, my chapter is moving into early voting/mobilization mode.
I'd urge all greek peeps to do what they can, particularly if you live in a battleground state. ...RBL, I know you and the bruhs are holding it down in Michigan, right?
