Conservative women are more likely to value traditional family structures and gender roles, and thus place a higher priority on getting married and having kids. Even controlling for age, etc., conservatives are 25% more likely to be married than liberals.
I think lots of “liberal” guys would be happier in a conservative environment,[1] with the greater social structure and narrower horizons of conservative society. If what you really want is to settle down, have kids, and live a normal life, you might be making yourself unhappy trying to hack it in the NYC or SF's dating market--which is full of ambitious, individualistic people who aren't placing a high priority on those things. Consider that you might be happier moving to a red county and finding a conservative woman whose life priorities may be more aligned with your's--even if you may have abstract disagreements on immigration policy or the long-term effect of the welfare state.
[1] Of course the opposite is true--but liberally minded people who can't wait to leave Iowa is a well-known trope. We don't talk so much about the folks who went to the big city for education or career opportunities, but would actually be happier in Iowa.
Lol at the emergence of all these archetypes about the dating market etc. you’re not out buying consumable goods; you’re looking for people to spend time with and enjoy each other’s presence. Everytime I hear people complaining about this it is always transparently clear from their own words that they are the problem. Conservative environments are not a plus, but instead a reservoir of retrograde perspectives and unimaginative implementations of false concepts of historical precedent. The lamest approach.
