Is Barack Obama's website conducting an outlawed-in-Minnesota raffle? The Minnesota Gambling Control Board thinks giving new donors a chance to meet Obama backstage in Denver is worth investigating. The Strib's Randy Furst says only nonprofits, not campaigns, can conduct raffles in Minnesota. The raffle standard: it costs money to participate, it's based on luck of the draw, and something of value is at stake. Obama's campaign sounds like it will argue the winners won't be random.
