Sessions fooled Trump and many, many conservatives. But as they say, the proof of the pudding is in the eating. After Sessions had been in place long enough to demonstrate his bias, Trump was profoundly disappointed and Chuck Schumer was thrilled and delighted. Schumer going so far as to threaten Trump against firing Sessions tells any honest, objective person all they need to know.
Maybe it’s a different scenario.
Could be Sessions didn’t start fooling anyone until after taking office as AG, when he made the swamp think he was on their side.
This is what he would need to do if he were in fact draining the swamp.
