Clinton also polled higher than Trump. Biden has the same issue as Clinton - the inability to excite. His base very neatly overlaps Clinton's who weren't enthusiastic enough to win 2016. This "everyday man rural Joe" claim DNC heads and centrists have tried to peddle is going to backfire when no one goes out to vote because they find someone pleasant. It also ties back to the myth of "rural voters reject progressivism" when time and time again showed that economic progressivism is extremely popular with rural voters and cultural progressivism was not. When you lack the former, rural populations inevitably reject the latter. Moderates didn't do best in rural communities in the mid-terms - they did best amongst upper middle class suburbs, which will always swing back to Trump come election time because rich people vote with their wallets as they continually do.
