North-central MN is moderately DFL... but that is pretty sticky. Except in GOP wave years, the DFL will eek out a 5-10 point win every time.
Bemidji is kind of like a larger metro: Within the city limits it's strongly DFL. This is from college students as well as the fact that the old fogies just tend to support Democrats and be generally pretty liberal.
The surrounding townships are more GOP friendly, especially on a presidential level... even so they still tend to pick the DFLer.
The district to my west on the state level has tended to be divided between a 55/45 GOP favored white population and a 90-10 DFL favored Native population. So Democrats tend to win there, again, except in GOP wave eyars (like 2010).
Duluth is very DFL friendly and is genuinely liberal. The Iron Range is also very DFL friendly... but is more socially conservative. They love to talk about fishing and hunting... it dominates life in most of northern MN. If you haven't gotten a deer yourself... someone will most surely be gifting you venison sausage for the holidays. And it's not just rifle hunting... but bowhunting as well cuz hunting is that much fun to people. (personally I think it's boring as hell)
When you hit a deer here... it is expected that you will try to salvage some of the meat. Might as well try to get your money's worth
