CMV: Biden would go down as the best president in a long time if he didn't try for a second term and let dems have a proper primary.
Afaik Biden kinda disliked Obama privately a bit since he was sidelined in 2016 . I think he privately told his aides that "obama never completely believed in me " and very strongly believed that he would have beaten trump if he was the dem nominee instead of Clinton.
Obama and Biden don't have that good of a relationship since then. As his term progressed it was clear that biden largely relied on his wife and son for advice instead of his cabinet whd and didn't even meet them all that much .
Since his strategy to avoid criticism was just not talk much about it to anyone, he was very offended when he was persuaded to drop out . The party wanted a mini primary since they (or atleast pelosi ) didn't believe that she could win it and welp that's what happened .
But they had no option other than nominating her since biden endorsed her after dropping out . Now imagine if biden agreed to not run again as soon as he started out , maybe he would get insecure about the party and they inturn would be much more firmly behind him. In a healthy primary the dems have a much better chance to nominate some one better and I think Trump wouldn't win then . Harris ran a bad campaign and still managed to nearly win Wisconsin . A slightly stronger candidate would probably win the rust belt and Georgia as well. ( Maybe not Arizona and NC but this is the worst case )
Biden would then leave office with a much better legacy and legislative accomplishments.
