I get the theory sounds cool, but in what way is Killary protecting Obama?
You have to jump through a lot of hoops to spin a scenario where she needs to fall first for Obama to go down re: Obamagate
However, the less interesting option but more obvious on it's face given the context was that he was just referring to Graham and his obstruction, teasing that it didn't matter anyways because he will be gone by the time they were ready to come after Obama.
I just don't see how the former in any way makes more sense than the latter, other than anons wanting to feel like they cracked some code.
