The marketing geniuses at 7-Eleven have found a way to engage their customers this election season. It's simple and brilliant. Right now, whenever you get a cup of Joe at any 7-Eleven, you can choose an Obama (blue) cup or a McCain (red) cup. Essentially, every cup is a "vote." Naturally, the whole campaign (not a play on words, really) is supported by a nice, clean Web site. And given the fact that 7-Eleven sells one million cups of coffee a day, the promotion has the potential to generate fairly relevant, significant results. As you'll see on the Web site, they've done this before, and their previous results have tracked closely with those election outcomes. Indulge yourself and take five minutes to check out this clever concept.
