As Zero gets hit on so many fronts, this looks more and more like an attack on his presidency. Who would benefit from that?? The Clintons for one. She would be the logical choice to be appointed VP under Biden should he become president. This would make her run in 2016 easier for her. Biden would get a chance to be president for a couple of years. This looks like a showdown between the Clintons and the Obamas and the Clintons have a lot of friends at the IRS. She also does not want to be blamed for Benghazi and will throw Zero under the bus the next time she has to testify. The Clintons also know they have to get the press out of zero’s camp and into theirs. Zero has worn out his usefulness and it will take even more than this to make him resign. You can be sure a steady stream of sh*t will hit the fan until he does.
If she is not thrown under the bus first.
A solid hypothesis, but it will take a lot for Behghazi plus the mess she made of foreign policy to be discounted.
