Do daughters make you more conservative?

Dalton Conley and Emily Rauscher report:

Washington (2008) finds that, controlling for total number of children, each additional daughter makes a member of Congress more likely to vote liberally and attributes this finding to socialization. However, daughters’ influence could manifest differently for elite politicians and the general citizenry, thanks to the selection gradient particular to the political process. This study asks whether the proportion of female biological offspring affects political party identification. Using nationally-representative data from the General Social Survey, we find that female offspring induce more conservative political identification. We hypothesize that this results from the change in reproductive fitness strategy that daughters may evince.

I don't yet see an ungated copy, do you?  By the way, I applaud the authors for their "stones" in writing the last paragraph of the paper, such as:

The conservative emphasis on family, traditional values and gender roles, and prolife anti-abortion sentiments all stress investment in children – for both men and women. Conservative policies mirror the genetic interests of women, writ large. They attempt to promote paternal investment in offspring. Further, they stress investment in conceived offspring – “a bird in the hand is worth two in the bush.” In short, Conservative policies support the genetic fitness of women by capitalizing on each pregnancy, reducing male promiscuity, and increasing paternal investment in children. Such policies may impinge on the freedom of parents’ immediate offspring, but they increase the expected number of grandchildren via daughters.

I'm not sure that's true as stated, but it does deserve further debate.
