I believe you may be confusing 2 different states, little house was based in Missouri I believe.
As for MN, it’s the ONLY state Reagan lost in 1984, the ONE and ONLY. That tells me they’ve been lost for a very very long time. Mondale is/was a bum so of course they voted for him. Sad
Actually the Ingalls family lived in Walnut Grove, MN from 1874 to 1876 before crop failures drove them away. There’s a museum dedicated to them there.
And yes, this state is polluted with liberals mainly in the big cities. I’m glad I live in a conservative county.
