I seriously doubt it but I really hope this is a wake-up call for Democrats. I remain convinced that Biden voluntarily stepping down and permitting a younger more charismatic figure in his place will be all that is needed to win, and I say this for a few reasons:
By the polling, age is a huge issue for a significant majority of Americans, with it clearly harming Biden more.
Any youthful semi-in-the-shadows candidate will be fresh for Americans, who will be excited for anything different.
The right-wing talking-points won’t be pre-written.
By Biden & Democrats getting ahead of this and saying, “look we recognize the electorate’s concerns and what’s at stake and we know the people by large majorities don’t want either President, so we’re responding,” they would get major points.
Call it a reverse-October surprise.
That being said, this is the earliest debate ever and Trump still needs to go through sentencing in July. People won’t really remember this debate, but it certainly did not help Biden in any capacity.
