Minnesota house seats are going to be a mess.
Not certain what you mean by MN house seats being a mess - but the GOP will flip US House seats 1 & 8 from Dem to GOP. House seats held by Eric Paulsen and Jason Lewis are iffy - could go wither way. If Paulsen and Lewis lose, the they flip from GOP to Dem.
I see the worst case scenario is that the seats remain as is now, i.e. 5 Dem and 3 GOP. But the best case is 5 GOP and 3 Dem.
