My wife has been an Obama supporter from early on in the primaries. I stayed neutral during that period, but since each party has settled on their candidates the choice has become easy. The McCain campaign was shaky to begin with and now appears almost pathetic.
But if you still need convincing and you’re in to tech (and who isn’t these days?) there is a web site specifically to help along your convictions. Here is a video of tech endorsements from the site. Oh, and by the way, the site was built using Drupal, a system we use more and more.
