Is there some reason, statute of limitations or something else that makes this such an urgent matter? Why not hedge the bets a bit? Hold off until January 21, 2016 to make the referral, and use all this as fodder in the campaign.
Then, right off the bat, submit to the new AG (assuming Holder is gone, and Zero hasn’t issued blanket pardons to all his co-conspirators) for action.
Heck, a guy can dream, can’t he?
Remember Gerald Ford pardoned Nixon for anything he MIGHT have done. Obama can do this with everyone who worked for the government during his term. Now, the question is: Will he pardon a white woman?
