Believe it or not, but IMO it'll be China who decides about the US election 2020... China has enough material about Biden, so can choose any of the two, depending on the concessions made...
Authenticity of emails confirmed: Joe Biden was part of Chinese deals: https://www.rt.com/usa/504204-biden-email-china-deal-authentic/
Latest rumors: some sources say that the FBI is investigating this as a money laundering crime. I'm sceptical of the FBI: if they investigate it, then highly-likely to cover/protect the Biden criminals, IMHO.
