Jesus, what a shitshow. I didn't have much to drink during the thing, but still woke up with a massive headache. If I was in Biden's place, I don't think I'd have been able to resist the impulse to walk over and punch Trump in the face.
He was a toddler on Adderall - fixated on one stupid idea, and wouldn't/couldn't shut the fuck up no matter what the adults were talking about. Seriously, he must have doubled his usual dose; he was completely unhinged. After about 15 minutes I was wondering if it was over the top even for Trump supporters, but of course I know the answer to that - not even close: they wanted more WWE-style bullshit.
Yes, it will hurt Trump short term because it turned off voters who haven't made up their minds yet; but anyone who fits that description at this point is by definition an idiot, and they could swing back again; you can't underestimate stupidity or predict what it will do. Trump's strategy was to fire up the base, because that's the only strategy he can comprehend, and I'm sure he succeeded. Maybe that will make it close enough for the election-stealing apparatus to work. Take nothing for granted: we're in for a rough ride.
