An even swing to an election in which the Democratic nominee for President gets a 13% edge in the popular vote looks much like this as an even swing. Of course few elections really are even swings (nobody will ever get 102% of the vote in Dee Cee). Allow 2% for third-party nominees and people writing in such entities as Jesus Christ, Santa Claus, and Darth Vader. and the election goes to 55.26 to 42.26 or so.
The closest analogue to that would be a partisan inversion of George H W Bush vs. Dukakis 1988..
To suggest the opposite in which President Biden were getting clobbered by 13%, the map would look much like this:
This would be much like a partisan inversion of Obama vs. Romney in 2012.
