Here's the thing about PA. I don't think it's a wrap yet and here's why.. It's not about 2016. We know Hilary ran a horrible campaign. We know this. 2016 was an outlier in terms of a Democrat losing the state..
However, I believe turnout in 2020 was around 76% (I'll recheck this) for PA and Biden won by around 80,000 votes or so. That's still close for having such a high turnout.
Compare it to 2012 and Obama defeated Romney by 300,000 votes.
Compare it to 2008 and Obama defeated McCain by 600,000 votes
A popular Dem in Biden with high turnout in the state vs. a horrible candidate in Trump who everyone saw on full display for 4 years and the margin was 80,000 votes... that doesn't sit well with me and is why I am cautious about the state of PA...
