I'm not sure Ben's math maths though.
Is it common knowledge that Joe Biden is too old to be President? Yeah. The media has been beating this shit out of this drum for a long time and between both them and now Joe's performance, it's obvious to most.
Is it also common knowledge that Donald Trump is the death of American democracy and a deeply dangerous, demented conman? Despite the media's best efforts to cover it as little as they can get away with....yeah, it absofuckinglutely is common knowledge
What happens on November 6? Joe still wins. When push comes to shove, more voters will be comfortable with a zombie Biden administration knowing that there is a presidential hand off to Kamala or whoever likely in the cards before the end of the term than they are with the end of Democracy. When you start seeing shit like "the end of our democracy" ranking in the top 1-2 issues on peoples minds in already wonky polling, believe it.
