Post-2020
Minnesota and New Hampshire shift left of the nation, while Nevada shifts right of the nation for the first time since 2004. While I don't have the districts here because they change every 10 years, I think it's notable that for the first time since splitting their electoral votes, Nebraska's 2nd will vote to the left of the nation. Under an even PV map with uniform swing, Donald Trump wins 311 Electoral Votes to Joe Biden's 227. This is compared to what would've been 320-212 in 2016. However, the tipping point state does appear like it will be more right of the nation (at least 3% more Republican, will get moreso as Biden grows his PV lead) than in 2016 (when it was 2.9%).
