It’s deeper. Obama called him a racist in South Carolina during the 08 primary. He ran a very dirty primary fight against his wife. He made his wife SecState, then shoved her out of the way, conducting diplomacy around her. And now, this Benghazi matter happens, and he exiles his wife to Peru.
The Clintons may not have any real love for each other, but messing with Hillary? That’s Bill’s job. And nobody gets away with calling him a racist, especially some man-child of a president who had not the discipline to fight the “right wing conspiracy”. Bill knows it’s over for Obama, and now, he’s made sure he is well placed to get his vengeance for South Carolina. And it’s a dish best served cold.
