According to Inside Flyer magazine (subscription required) the Barack Obama campaign has launched a points program for volunteers. Earning opportunities include marching in a parage or signing a supporter card (or getting someone else to do so) for 25 points, and working a phone bank for 50 points.
They haven’t published a redemption chart, and BaltimoreSun.com cites the campaign’s online organizer as saying the points system is primarily a way for supporters to measure they impact they are having on the campaign.
But really, this just formalizes a process that all campaigns have — what you give is a primary determinant of what you get. They could easily partner with the custom rewards engines at American Express or Diners Club, where enough points could be redeemed for a dream experience… Like Secretary of Commerce in an Obama Administration.
