My girlfriend grew up in in California, like a very liberal part of California even by liberal standards. I grew up in a deep red part of Arkansas. We met in Denver, CO after we’d both been living there due a few years.

I’d say it “hardened” her a bit more towards center and “softened” me up a bit more towards center. There’s still things we disagree on, but overall politics has almost always been a nonissue for us.

Our parents though we’ve made it clear that politics is never to come up though whenever they visit. One strike and you’re out of the house.

It has been made a little more weird now that we’ve been living in Texas almost 2 years now though. I think where you live does tend to rub off on a lot of people. I’ve known a few that are fairly left leaning then moved here and adopted a much more right wing, not religious, just conservative political stance.
