re: #344 NO SMOCKING GUN!
Biden is polling above 50% in states with 279 electoral votes, and millions of people have already voted. That is a big change from 2016, when Clinton was polling below 50% in most states, then late deciding voters broke decisively against her. Trump is polling above 50% in only 19 small states with 116 electoral votes.
the lack of any sort of third-party candidate is also of key importance here.
