Trump has an outside chance at MN but they dems have to run a bad campaign. With that being said it doesn't matter. MN won't decide anything.
Trump won't win MN
It's still a possibility, but very unlikely. 2016 might've been a fluke. I think they're more likely to vote for a left-wing anti-establishment candidate or centrist anti-establishment candidate, while Trump right now became the "establishment" himself in some kind of way.
I believe ME is more likely to flip though right now. I think recently I overestimated Trump in MN, but those are outright terrible polls, even if they overestimate Democrats. I don't think the Dems will win MN in double digits, but Biden will do well in rural areas, while Warren will do better in rural MN compared to other rural Rust Belt areas, and will do very well in the Twin Cities. The huge third party vote in MN will probably go to the Dems, and a lot of Obama - Trump voters will swing back. I don't think MN will be as competitive in 2016, and i was wrong before.
But MN stays a weird state, and will do surprising things in the future i believe so. It's the only state to go for Mondale, and it almost voted for Trump in 2016, they voted for Ventura as governor and are maybe the least partisan state, very swingy and with good prospects for third parties.
