When the Democrats put this kind of press release out that means they are GUILTY. This is the rule of thumb for the Democrat Party in the Clintonian era:
"When you are guilty of something, pin it on your opponent immediately so they won't pin it on you."
At the very least it shows desperation. Why in god's name would they want to keep this story in the news unless (a) they have nothing else to talk about; (b) they need to put up a smokescreen to hide their own complicity.
Given the established contacts between Mapes, Burkett, Cleland and Lockhart, this sure looks like a smokescreen to me.
