OK, assuming this is true... would you put it past the Democrats to double-cross the GOP on a handshake deal?
I'm inclined to think the leak isn't true, or not exactly so. Wouldn't surprise me if the Dems made noises like this. Also wouldn't surprise me if Bush wasn't going to make a big move on the Clintons anyway. Whatever Bill and Hill's guilt, there are real problems with establishing a precedent for incoming Presidents to use the Justice Department to investigate and prosecute ex-Presidents.
Sooner or later a Democrat will be President again. They are shameless bullies and will stoop to any justification to savage their foes and further their interests.
Alternatively, if the Democratic Party were to succeed in purging itself of Clintonian corruption and thus in surviving, future Democratic Party presidents would presumably be as little like Clinton as post-Nixon Republican presidents have been like Nixon.
