- Biden's 6-point loss in Texas [1] was the slimmest margin since 1996 (and 92 and 96 featured Ross Perot, a strong third-party conservative); the margins for 2012 and 2016 were 16% and 9%, respectively.

- North Carolina went for Trump by just 1.5%, and has had similar slim margins since Obama's 0.3% victory in 2008 [2]

- Colorado and Oregon both went blue by ~15% margins

- Montana has been reliably red.

- Florida has become more and more reliably red, but not as much as Ohio (which lost a vote) has.

More guaranteed-blue states (CA, NY, IL) lost votes than guaranteed-red (WV), but this isn't a seismic, immutable shift by any means.
