As a leftist man, I believe that men are better off not pursuing progressive/feminist/leftist women for long-term relationships.

To be clear about my political views, I'm something of a conservative Marxist-Leninist (in short, my ideal society is something akin to modern China, the USSR, or Putin's Russia), and I'm far left on most political issues [besides feminism, which I'm far right against]. In spite of that, I think dating is easier for men when they pursue dating pools with mostly conservative women, and here is my reasoning.

1. Infidelity

This point is my most straightforward one: 71% of conservative women think cheating is always wrong, compared to 36% of liberal women. The literal majority of liberal women think there's room for nuance as far as cheating goes. I'll get more into sociosexuality later, but liberal women have more unrestricted sociosexuality, and unrestricted sociosexuality predicts adulterous intentions, whereas restricted sociosexuality predicts better quality relationships. Sounds like a recipe for disaster already.

1. Alpha Fucks Beta Bucks

I barely think we need to define the phenomenon, as we've heard enough stories from the men here about women reluctantly romanticizing the stable average guy while sexualizing and lusting for the unstable hot guy. Interestingly enough, I found a study describing the phenomenon. The research analyzes the dual-sexual strategy hypothesis which claims that women select different men for short and long-term relationships. Unsurprisingly, it found that American women select genetic traits (sense of humour, masculine, good body, athletic, good voice, and good-looking) for short-term relationships, and material traits (stays at home, considerate, patient, good income, high social status, successful career) for long-term relationships. However, the study also found that sociosexuality (willingness to have casual sex) was a good predictor for adherence to this strategy. To be specific, women from India envisioned the latter kinds of mates for both short-term and long-term relationships. This means female conservative daters don't compartmentalize men as hookup material or husband material. In other words: conservative women have no concept of alpha fucks beta bucks, as they give the stable guy full sexualization as well as romanticization.

1. Sociosexuality

Though it should be common sense that conservative women will have lower sociosexuality than liberal women, I suppose I have to justify myself in claiming so. Unrestricted sociosexuality is associated with earlier sexual experiences in life, and greater lifetime partners. Conservative orientations are associated with both older age of virginity loss and fewer sexual partners. That proven, I'd like to delve more into the implications of unrestricted sociosexuality, which is more apparent in liberal women.

1. Superficiality In General

I noticed that lots of bluepillers will try to diminish the tradcon cause by making claims based on feminist theory that feminism actually benefits men who are concerned about superficiality in dating since feminism breaks down the norms dictating that men should be taller, sexually experienced, etc. That couldn't be further from the truth! Are you a man who complains about how women prefer guys with experience? Well women with restricted sociosexuality rate chaste men as more desirable. Do you complain about women having height preferences? Well endorsement of male gender roles (which is a conservative thing, duh) has a weak association with height preferences. So if you want a woman who doesn't care about height: go for a conservative. Complaining about how you don't have enough looks and status to get women? Well sociosexually unrestricted people value physical attractiveness and social visibility over personal qualities in a romantic partner. Worried about constant mate-guarding? Well restricted sociosexuality predicts commitment, which is negatively associated with physical and sexual attraction to an attractive person. How about the spark? Plenty of men will complain about how women don't want to build attraction over time anymore and dispose of men if there's no initial attraction. I admittedly have no data on what type of women care more about the spark/initial attraction, but I think we can conclude from the aforementioned research on sociosexuality and bluepilled women's frequent defense of the spark on this subreddit that liberal women will favor the spark over romance-building. What if I told you that this whole "the spark is an inexplicable feeling of romantic attraction" mantra is a lie, and the spark has actually been proven to be tremendous initial physical attraction? In other words, if you hear women on PPD or elsewhere mention the spark from now on, just know that "the spark" is a dogwhistle for physical attraction. Overall, this feminist theory that conservatism is what creates superficial dating standards and liberal women will be more forgiving couldn't be a bigger falsehood.

1. Actual Politics

This is the section that will best directly answer my title prompt. This study reports modestly greater relationship quality among those who report being politically conservative. It also reports that being partnered with someone voting Republican was associated with higher relationship adjustment and commitment compared to being partnered with someone voting Democrat. Interestingly enough, Republicans paired with Democrats tended to report substantially lower relationship adjustment than if paired with Republicans. That means that dating a conservative is a good guarantor of a stable relationship. Still not convinced? High sociosexuality in men is associated with attitudes related to sexism and traditional masculinity, while low sociosexuality in men is associated with liberal feminist attitudes. Contrawise, unrestricted women describe themselves as more liberal and unconventional.
This means conservative women and liberal men have similar romantic/sexual goals as they both have more restricted sociosexuality! Need I say more?

1. Misandry

Now here's a common scenario you'll see on this sub and elsewhere. A man gets bitter about his dating record, starts generalizing women, then a bluepiller responds with "why date women if you hate them so much?" However, these are the same women who condone or validate blanket statements on subs like r/dating such as "what the fuck do I need a man for" or "90% of men in the dating pool are trash anyway." Reverse the genders, and a woman will ask you why you even date women if you hate them so much. I'd like to throw that question back at feminists and ask why THEY still date men if they hate them so much based on the 2 common statements? I could say more about misandry, but I'd rather use this section as my gotcha paragraph.

1. Independence

This might be my more controversial section, but I think that liberal women's independence makes them more unfit for long-term relationships. When it comes to feminists and dating, they push mantra along the lines of "I'm happy being single since I have my cats and friends! I'd enter a relationship if the right man came along, but I'm not actively looking for someone and could go the rest of my life without a relationship." From what I've seen, conservative women feel more pressure to be in a relationship whether it's out of loneliness of conventions. I know bluepillers are going to start saying "but relationships are better when people WANT to be together rather than NEED to be together, because those romances are based on love." Lol, liberal relationships are literally more unstable as proven by the research above, and educated liberal women initiate divorce at insanely high rates. Some relationships those are, lmfao. Do you know why arranged marriages are known [especially among South Asian communities] for having very low divorce rates? Relationships work better when their foundations are strongly defined roles and transactions. Passionate love is fleeting and volatile, which makes relationships based on such fleeting and volatile. And obviously, women who see relationships as a need tend to be more reciprocal, less flakey, and ghost much less than liberal women who are obsessed with the spark and using men for free dinners if they don't feel initial attraction. I know some people will call me insecure, but I'd rather feel needed by a partner and work that dependency into passion than start a relationship based solely on a spark that dies out after the honeymoon phase. College educated women initiate divorce at rates of 90%! I know some bluepiller will say "maybe use this statistic to learn why they're so prone to initiate divorce" but that just places a huge burden on men, when they're obviously better off avoiding such women altogether than putting up with such romantic instability.

Conclusion

Conservative women have both lower standards and higher long-term quality: so perhaps men should pursue them more.
