ARe you guys sure of this? I mean, there's a camera guy in the back there. You don't think this was someone's back yard party? Let's be fair to the poor little guy...of course they could be milking this for some future ad campaign....targeting seniors...
I really don't know the details behind it. But even a backyard party meant to act as a political rally will involve the person holding it inviting people from far and wide. The idea with these things is to show a wide backing. And the mic in Kerry's hand indicates they were planning for a bigger crowd.
