Biden is up 17 with white women. Wowzers.
I've mentioned her before and it's totally anecdotal, but the elderly lady who lives across the street from my parents hasn't voted for a Democrat since Kennedy (IIRC). She's planning on voting for Biden ("I like Joe Biden", "Trump lies and lies", etc. etc.)
Again, purely anecdotal and not meant to indicate a trend by itself, but when we combine that along with Biden's polling numbers, I have to think there are more like her.
I've seen a bit of this happening in my area as well. I'm not sure why all of these older voters have waited until now to finally wake up, but I'm not complaining.
Self-interest. The Republicans would only have come for their healthcare last.
