1. Biden's kid got the role because he's Biden kid. 90%+ of people don't like this. But it's not hardcore nepotism and most have given Biden a -1 or -2 for that and looked past it.
2. The logical connection between Hunter's board role and Biden's actions regarding Ukraine never made sense. This story has been around for 2 years and we never get the true connection. Firing the prosecutor makes no sense if you actually research it, because the prosecutor was known to be crappy and the new guy re-opened these investigations.
3. Of course Russia wants Biden to lose, and will covertly help Trump. Because Trump wants better ties with them. I don't think most would want a country, especially autocratic Russia, covertly helping one side and not the other.
All in all, this is clearly smear and diversion.
