I don't signal my political leanings in profiles, but they can probably guess anyway. There are a lot of women on dating apps that include statements such as "If you're a Trump supporter, swipe left."

Generally speaking, I don't have a firm aversion to dating conservatives. However, I consider Trump supporters to be a different group entirely. I would definitely not date a Trump supporter, in part because it also signals a defect in their personality and/or ability to think rationally.

In the end, I tend to stick to dating left-leaning women. I enjoy discussing politics with people that have opposing views, but you don't necessarily have to make those type of people potential life partners. I think you can remain diverse enough by simply keeping people with opposing viewpoints as friends and acquaintances.

Lastly, I'll add that the 'don't talk politics on a first date' thing is a little overblown, especially depending on who you date in DC. There are plenty of people living around here who see their strong political opinions as a core personality characteristic, and want a partner who is similarly energetic about certain issues. I've had experiences where talking about politics during the first couple dates has charged up the chemistry in a good way. You just kind of have to play it by ear depending on who's sitting across the table.
