I think his "natural charisma" is explained by being an important guy with connections and a big, fat wallet. For mature women looking to build a second career like McDougall or Daniels, that's a "must fuck" guy and it has little to do with his non existent charm and flabby, aging body and everything to do with what he could fix up for them - or so they thought.
I am sure that both McDougall and Daniels target guys they believe could potentially help their careers - one way or the other. That's why both women are so keen to throw Donny under the bus when they can make more $$$$ ratting him out than by "staying loyal" to him. Do you think either woman has tender and affectionate feelings for that asshole?!.... No. If they had, they would STFU about how they fucked him and not try to peddle their stories to the trash tabloids.
Trump has about as much "charm" and "charisma" as my rectum. He's self-centred, egotistical, selfish, narcissistic, petty and spiteful. You think women don't notice that?! Look at how Trump publicly treats Melania. Does THAT show you what a kind, likeable charming guy he is?!... No, he's a nasty, domineering, shallow dickhead.
