Right, MAGA takes Trump's infidelities as a sign that he's a real macho alpha male. Harp being another mistress wouldn't cause a problem at all. They'd probably applaud him for it. But if Harp is there to cater to a feeble old narcissist who's too fragile to handle the news? Oof.
What folks miss is MAGA doesn't care if people think Trump cheated for the 1900th time. What worries is the image of an 80 yr old man wildly dependent on a clincially fangirlish 30-something who he appears to use as a kind of human emotional support blanket as his faculties & political power fade.
