Hillary has some stuff on Obama, if leaked, could probably start a fire. Obama knows if Hillary goes down, she may sing a song about him. He can’t let that happen now. Obama is better off letting Hillary run free, and gambling she will beat the person the GOP elects. If Trump or Cruz win as President, Obama and Hillary may be exposed.
Agree that Hillary has the goods on Obama and for that reason she will not be indicted or prosecuted while zero is still President.
However, should she win the nomination, but lose the general election to Trump or Cruz, zero will likely issue her a full pardon for any crime she may have committed while Secretary of State to ensure her silence. It will be one of his last acts as president and publicly announced the morning of January 20, 2017.
