Obama was an economic and foreign policy disaster. The smartest woman in the world ran for his third term. There is nothing hard here. This is not wave mechanics.
I'm not so sure. Mueller led the coup attempt, wrote the impeachment guide and handed it off to the Democrat controlled House. He gets to go home and watch a frothing at the mouth bunch of Democrats investigate and attack.
The finest lawyers I know tell me it is no place for a prosecutor to exonerate anybody. Mueller took it upon himself to announce he was unable to exonerate his coup target.
