I haven't been able to find anything about that on the net, but my Google-fu is known to be inconsistent. If this is a false rumour started by Republicans to divert attention from what they've been doing (or to make an "everybody does it" excuse sound plausible, not that I would consider it an excuse), it'd be nice to be able to expose that. On the other hand if it turns out to be true, it'll be uncomfortable but very important for Democrats and other Kerry-supporters to expose that and to call for repudiation of the folks doing it. I'll keep an eye out for more information.
