If she were a gold digger, why would she wait until she’s almost 80 to come forward at a time when other women are making accusations about him? Maybe she’s not a lady by your definition, but that doesn’t mean she wasn’t a whore looking to sleep her way to the top but just a naive campaign worker.
Because now is a cash in time. Also, in return for money (career), she stayed in a hotel room with him. She got paid for her companionship back then. She sold her dignity, and she worked for that old communist.
She isn’t some babe in the woods. And was she married at the time? Did she tell hubby about her sleeping arrangments?
