What Senate races see the biggest leftward+rightward swings from 2018?

[Pericles]

In terms of rightward shifts, it has to be one of IN/MO/ND/TN/WV, since these were races in deep red states which were heavily contested in 2018 but not this year. (If I had to pick only one of these, I’d go with WV.)

MO might not be that big, Hawley won comfortably in 2018 too and he's a polarising figure which puts a hard ceiling on his support. Something like MO 2022 is plausible.
