I sincerely hope this turns out to be Obama's "Swift Boat" moment!

I'd be a lot more circumspect here. The Swift Boaters were in a different position. They were coming forward with specific information that was within their knowledge and not yet available to the public. They may have been motivated by opposition to Kerry, but their possession of new information gave them cover from the accusation that they were simply political operatives, leveraging their military status. I don't think that's the case here.
