We have seen recent research suggesting that men with daughters are more likely to be Republican and a study finding that men with sisters are more likely to be Republican. *
The study of men with sisters was conducted by researchers at Stanford Graduate School of Business and Loyola Marymount University. A report from Stanford about the study concluded, “Watching their sisters do the chores ‘teaches’ boys that housework is simply women’s work, and that leads to a traditional view of gender roles — a position linked to a predilection for Republican politics.”
Also, in 2012 65.0% of white men with wives voted Republican compared to only 50.6% of white men without wives.
