Then she should have gone to the police. Why does she have to tell a number of people? Just because it's convincing for you doesn't mean it happened. I don't know if it happened or not and neither do you. She should have gone to the police immediately and got a lawyer for herself. I am sure she would have got plenty of lawyers and even funding if it was against Biden.
Do you really need it explaining to you why she might not have wanted to go to the police? What planet are you on where a woman is raped and her immediate response is to phone the police and a lawyer.
As for the Bernie camp voting for Biden debate, I don’t see why it is hard to understand both sides. Both are understandable to me. Personally I’d hold my nose and vote for Biden as the lesser evil; but make no mistake that he is an ‘evil’, and people could have a multitude of legitimate reasons for why they cannot bring themselves to actively vote to install him as President.
