Coupla things . . .
No matter who heads an investigation on any of the three or more Situations involving the White House (Benghazi, The IRS, or the AP, plus a couple more in the pipeline) it will be "Politically Motivated" . . And it's outcome will most certainly be "Political" in nature.
I don't see any Impeachments and the chances of anybody outside of a couple of mid level flunkies going to jail in the future on any of these. However "Convicted Mid Level Flunkies" will tell investigators about who ordered these things to be done and I'm betting that before it's over, at least Timothy Geithner will have bus tracks over his tax dodging ass too!
BUT . . it has a hell of a lot to do with the Years of 2014 and 2016, because that's when the direction of the country is determined. If the Republicans can show the 5 to 10% of the Americans who vote from the center that the Democrats are corrupt, and not to be trusted to run their government, then perhaps (nothing positive here) the Republicans will be given a chance to run the country "Unfettered". But that may not be a good thing either, because the Democrats held "Unfettered" power from 2008 to 2010 and did absolutely nothing with it except pass a law none of them knew anything about.
And . . whether anyone ever proves that O'Bozo was at the head of any of the current (or future) scandals that are being (or will be) investigated or not, we'll know one of two things. Obama isn't the real president, because he knows nothing about the operation of his Administration, or . . He was the man who was responsible for all of it . . In which case he should be prosecuted for "High Crimes and Treason" . .
And hopefully, before it's over, either O'Bozo will throw Hillary Clinton's Fat Ass under the Bus or she can be implicated and proven to be, at the least, incapable of acting in an executive position, which will exclude her from the presidential race in 2016.
