I tend to agree with you, but not without reservations. Secret hate vote does work both ways.
I think overtly Biden supporters will continue to support him. Trump will get a huge secret voter hate vote. Because Americans at the core are still Wild West and antebellum denizens in their minds. Lip service is paid of course to notions on which an evolved society should be based. All theoretical. Trump will win. THATS America. Now and always has been since it’s inception. American History has been bloody at best replete with base instincts. Silly lost dream, this, our America.
