Obviously WV and MN are probably are going to have some of the largest swings.
Surely you mean TN? My understanding is that Klobuchar has nothing to worry about this year even if MN may be in play at the presidential level.
Totally agree about WV though and don't see how there can be any other answer to the "rightward" part of this question.
I forgot about Tennessee, but no I meant Minnesota. Yes, Klobuchar will easily win again but it's going to be a closer high single digits, low double digits margin than her blowout in 2018 where she even won MN-07.
