@lednaBM It looks like media are capitalizing on progressives being vulnerable to doubt, progressives being perhaps a little neurotic. This seems to be an Achilles heel.
As for Biden, and I am speaking as a European, it is ok to vote for the ideas and ideals. It being all about the man is a dubious concept from the far ends of the spectrum to start with.
If you don't think Biden is up for it; trust the system. There are enough capable people lined up. That is why it is called a democracy!
