I feel there is much more to this question than dating from the opposite side of the political spectrum. Liberal or conservative has no impact on the personality of the person. I also think someone's political views aren't anywhere near as important as how they view the home, their role in a relationship, and where they want to see themselves in like, 40 years. I would NEVER date someone who make politics what they are. You see this in MAGA's and SJW's sometimes. Politics shouldn't replace a personality.
I, being a conservative, started dating my best friend in 2007 who was more of a moderate and supported Obama. Fast foreword 12 years, and my now husband has become more conservative than I am. But nothing about my love for him have ever mattered because he is a wonderful, sweet, amazing guy. I doubt that would change if he were voting for Biden instead of Trump.
