I walk around Downtown at night & feel perfectly safe. Our state voted for Obama by a landslide in the primaries, though there are a lot of German Catholics, our governor is a Dem, so is Milw’s mayor. Milwaukee is mainly liberal (hmm..I think 75%) while ‘burbs vary (I live in one that’s 75% Rep).
See my Q link regarding how “outgoing” all of the Midwest is. It’d be good info for you to know if you did decide to move here, as you’ll see it’s likely you’ll be fast to make new friends.
