I think the world of Mike Lindell. He's a good and decent man. I would hope he would not run for Governor. He would be the most unfairly attacked candidate in history if he ran.
Tim Walz is an incompetent who refused to protect the citizens of Minneapolis from mobs when their local officials would not. Unfortunately, I cannot see Mike Lindell defeating Walz at the polls.
Lindell's recent meeting with Trump, along with his shilling for him, gives the Democrats a sizable arsenal of completely fair attacks, so I wouldn't worry much about unfair attacks.
