I’ve thought since the election that it was great news for us that Biden decided not to run, because I think he would have been a much better candidate than Hillary with the sort of cross-over voters that put Trump over the top. I don’t know that he would have taken Ohio, which Trump won with such a huge margin, but I totally agree Biden would have had a great shot at keeping PA, WI, and MI blue, which would have left Trump 10 electoral votes short of 270.
Biden has never really been hit because he’s never been relevant. It’s always easy to be the beloved candidate that might have been. When McCain ran Romney would have done much better and when Romney ran Jeb could have made the case. I’ve heard THAT before. It’s not to say that Biden couldn’t have won but we just don’t know because it never happened and he was never criticized. He never had the spotlight on him. For the record, he ran against Obama and Hillary in 2k8 and got 1% of the vote.
