A: Even for that lying bastard in the Oval Office,

this is a string of crap that's amazing.

B: He still has no responsibility for ANYTHING(unless he thinks it's good, then no matter when or how it happened, he wants credit).

C: Mr. President, you're a slandering little shit. 
If anyone has a problem with me putting it that way, when he's throwing around accusations of treason, well, he can damn well deal with being called what he actually is.

In fact, it’s those hardliners who are most comfortable with the status quo. It’s those hardliners chanting “Death to America” who have been most opposed to the deal. They’re making common cause with the Republican caucus. (Laughter and applause.)

If Obama had said that the Republican caucus is making common cause with Iran’s hardliners, it would have been an unambiguous accusation of treason. By phrasing it the other way around–the hardliners are making common cause with Republicans–Obama gives himself a slight margin of deniability. But either way, it is a disgusting slander.
