Apparently, there is a degree of narcissistic personality disorder one can have the prevents them from being able to accept losing an election. See Mittens, McCain and Hellary.
This isn’t personal. Romney disagrees with Trump on policy and is trying to instigate intraparty food fights and distract POTUS. It all goes back to the 2012 GOP “autopsy report” after the kenyan wiped the floor with magic underwear boy. The GOP wants to move the party to the left and support the progressive agenda. The GOPe led by Romney desperately wants to turn the US into North Mexico and Trump opposes that.
Obama spied on Mittens and he knows it. But he is to much of a coward to say it. He thinks he can regain his manhood by taking cheap shots at the Man!
