There’s about at most 1.5 million votes left in PA. Biden is down almost 700K. So he would need to take about 75% of the vote to crawl back even. There’s nothing in any of the other numbers that suggests Biden could do that.
Here’s what I figure. Without PA, WI and MI, AND losing AZ, Trump stands at 250. (I think). PA alone gets him to 270. Any two get him OVER 270. Not sure about those weird states that split their votes.
