She outs herself and has done so on numerous occasions:
All that vast inside-the-Beltway knowledge and she deigns to converse with us? Just wow!
Theories schmeories. Here's what I know. Trump was a boorish, tacky, rude, thin-skinned, narcissistic oaf as a candidate in the primaries and in the general election. Using my powerful deductive reasoning skills, I'm going to assume this behavior is simply ingrained in him and will be his MO until his life on earth is done. He will always be settling a score, dissing someone, calling people names and whining because so few people speak highly of him. (One thing could make my assumption wrong -- he turns his life over to the Lord and lets Him make a new man out of him.)
I hope Sessions makes Trump fire him. I would highly recommend that he hold his ground and refuse to be bullied by Trump's incessant whining about him. Trump knows it won't go down well if he fires him. He would have already done it by now if he weren't concerned about the blowback. Surely he realizes his other cabinet members and staff are all looking on to see how Trump is going to handle this. Airing dirty laundry in public is so low-life and tacky, I just can't get over how people can continue to make excuses for him.
