My gut feeling is that through dubious means the Democratic operatives have gotten their hands on a juicy little bit of information that the Dems know can't be release unless there is an "official" investigation into the matter. I believe that this "information" will create a large media frenzy that will put the administration on the defensive and in a bad light.
I think the GOP has just taken the bait.
I saw desperate dems acting desperately, but that's nothing new.Just a unusual tactic.
