Could you be friends with someone that has opposite views politically?

I'm older, I've seen a lot of elections, and I've watched the division we have today grow and become militant and militarized over the years. I used to live in one of the reddest states, and it is beautiful, just amazing, but I'm Truly Blue, very left, I couldn't live in my home state now even if it was for huge amounts of cash, when I was young we just beat each other senseless over political differences, now I think it would possibly escalate way past fist fights. I don't even like to visit anymore. I've turned my back on some great old friends over the insanity of their political stances. I certainly couldn't date a Trump supporter let alone live with one.
