On AZ, I agree that it is shifting, but not in that severe a way to make it riden with Biden. GOP have today regained their 100k voter registration gap since the Democratic shift in 2018. It still, albiet slightly, is trending Republican. Also, apparently McCain was doing everything in his power to subvert Trump winning the state by refusing Trump to have a ground game in 2016. The AZ GOP chair is now a Trumplican, so the ground game can resume.
I agree we should keep observing PA registrations for any upticks in either candidates support, but I shall stress, you do not stop a realignment easily. I do not think the stimulus talks dissolving again changes much.
Why? Because its 2020 motherfucker, that's why. Since this nuclear tier bomb got dropped by Trump onto himself: Pence channeled the spirit of Tulsi and executed Harris, the media tried to cover for her with articles about mansplaining and a fly, BLM destroyed more WI suburbs, Trump and Biden duked it out about debate 2 rules and dates, and Trump got the greenlight for more rallies by tomorrow. I didn't even remember that what you mentioned just happened, and I wrote a short novel on it 2 days ago. Also, with Pelosi potentially doing the most full-retard move you can do by invoking the 25th Amendment to overthrow Trump via Congress somehow, I am not worried about the stimulus talks.
Like I said, will it matter 24 hours from now?
