You do know that tapes can be recorded up to several months or years before they're used, right? You can tape a bunch of different scenarios, do a little photoshopping, and ta-da! It looks like it's recent. How tough is it to tape several versions of "Bush bad, Democrats good", anyway?
You do know that OBL dropped a reference to "Fahrenheit 911" in that pre-election tape, right? That would make that it unlikely to have been "recorded years earlier."
