The GOP got NM in Bush 2004, carrying 40% of the large Hispanic vote there, but that was probably an outlier.
I think it's a weird dynamism because in bency favors Trump but the EC definitely favors Biden at the moment, considering he blasted Bernie in the rust belt states that were key to Trump's victory in 2016 (note, Bernie blasted Hillary in these states in 2016).
It's not impossible for Biden to win his hometown state of PA, and for MI to flip back considering Trump's comments, but, Trump could flip MN and hold WI considering the demographics in both states. I think WI is a coin toss and could easily stay with Trump considering the demographics there outside of the Madison-Milwaukee corridor, and a lot of the policies, i.e. taxes, gas taxes etc have trended conservative in that state lately. MN is tougher because the percentage of educated whites vs. non-educated is higher, but there are still a considerable amount of less educated whites outside the Twin Cities metro, and MN has been trending red for a long time so the Dems shouldn't be surprised if it turns red.
But even then, if Trump gets WI and MN, all it would take is for a shocker on the other end... (Biden takes AZ??!?!) for Trump getting big wins up north to be a moot point.
