Do you think Biden staying in, but NOT saying things like "only I can do it" ... shifting the tone as I described would alienate or harm the enthusiasm of this base?
I don't have a sense of how large this "base" is. Many people would count me in that based based on my voting and participation in GOTV in 2008, 2020 and this year. I'm not, though nor were most of the people I've worked with.
