All it means people know that you voted. Party registration isn't destiny. Maryland has a ton of registered Democrats but Republican Governor Larry Hogan is pretty popular there. West Virginia has a lot of ancestral Democrats, but it's a far cry from being competitive at the presidential level, though Democratic Senator Joe Manchin manages to survive.
Well you can simply outlaw/fine the kind of threats or rewards that you mentioned. And before you ask how one would prove it, it is more provable than sexual harassment or advancement for sexual favors, since it involves proof.
Outlawing that sort of behavior isn’t mutually exclusive of building sensible election systems that maintain ballot secrecy. It’s really unclear what you’re arguing for when you keep jumping around various aspects of elections (and sexual harassment?) in a totally incoherent manner.
