Not sure how relevant this is now, but in 2018 Vox (Yeah, that Vox...) put out an article highlighting some relevant options for Conservatives:

This is what I used when I did a search to see what was out there.

Although this quote really triggered me....

Peter Hatemi, a political science professor at Pennsylvania State University, agreed with Moreno’s premise that people are increasingly averse to dating someone who doesn’t share their political views, and that this is partially because of a rise in polarization. But, he explained, that doesn’t quite amount to discrimination. “It’s self-selection. It’s based on really strong data that like seeks out like,” he explained. “But there’s no discrimination against conservatives [on mainstream dating apps]. There’s absolutely no structural discrimination that prevents conservatives from dating.”

like bro, how is anti-conservative or anti-liberal bias when choosing a partner not discrimination? Sometimes I facepalm at the mental gymnastics that some of these "experts" come up with to justify their positions on things.
