There are a number of blue cities in the Midwest. What’s the lowest temp you want? I live in Lincoln, Nebraska and it’s pretty great: nice weather most of the year, low cost of living, blue city, tons of parks. Only downside is dealing with red state bullshit from the state government.
Omaha is a lot less left-leaning in my experience. It’s very purple. Lincoln is solidly blue.
I just recently purchased a house in Lincoln. Just quickly looking on Zillow for Omaha and home prices look to be very similar to what I was seeing here in Lincoln. Property taxes in Omaha are also a fair bit higher than Lincoln.
There’s other stuff too, like lower crime rate in Lincoln, better/more parks, LPS being generally a lot better than OPS, etc.
I guess it ultimately depends on what you’re after. If you want something more big city, then Omaha obviously has Lincoln beat. But for a more relaxed pace of life and for raising a family, Lincoln is where it’s at.
