It is also possible that "Garci" is Gwen Garci, sensational bombshell model. She's definitely the prettiest suspect. If we were reporters hoping for an exclusive scoop with "Garci" we'd really want it to be this one. Come on,don't you remember the picture in the page just before this?
So, OK, there are problems. For example, her voice sounds nothing like that on the tape. And frankly somehow we don't see the Garci on tape prancing around in a thong. You MIGHT see it, but that's your problem.
