@hightor,
Well, it should have been obvious a long time ago that Biden wasn't up for the task of both running for re election, or hanging in there for another four years, and the fact that there's now a mad scramble to find his replacement, tells me all that I need to know about the party he supposedly represents.
Harris certainly isn't going to be either a threat to Trump's chances, nor a viable leader for the nation, or party.
It's really that simple.
