That’s my hope. And you’re generally right about the polls: The RCP average, for what it’s worth, had Clinton +7.1 at this point, and has Biden +10 today. I don’t think the 3-point difference is all that significant when you consider how unscientific the RCP average is to begin with.
But, 2020 is not 2016. We don’t know what that means with regard to polling yet, but we’re about to find out.
