... desperately dependent on ATTENTION! When she doesn't get enough to satisfy her ever-increasing need for a fix, she escalates the malice and mendacity of her attacks to absurd levels.
The solution? Ignore her. Don't give her the satisfaction of your attention to her histrionics; don't publish her rants and accusations. Treat her as if she wasn't even there, like you can see right through her. Deprived of the oxygenating attention she craves, she will implode. Let her clean toilets with her toothbrush to earn a crust of bread.
Few, if any, will mourn her passing from the public spotlight. Yeah, I know the hard-core hyenas of MAGA-land will always give her some attention, but that will never be enough; her addiction is too far gone. She will shrivel and shriek like the Wicked Witch of the West when drenched with the cleansing waters of truth and common human decency until there's nothing left of her but her tattered, tasteless wardrobe. Then we can get down to rebuilding what Trump tried so hard to destroy.
