Actually, that's what I've been saying for a while. I don't think that CBS released them for that purpose, but I think that the Kerry campaign passed them on for that reason. The purpose was to fill the airwaves with so much garbage that when the Kerry fraud was exposed, the voters would just yawn.
I should add that this flood of garbage is an attempt to convince the voters that this is all about somehting that happened thirty years ago, and that they should all move on, much like the impeachment was all about sex.
