Why Have Women Become Left-Wing? The Political Gender Gap and the Decline in Marriage
提出美国政治性别差距的扩大源于婚姻衰落，婚姻使男性更富、女性更穷，并用数据证明离婚率上升会降低男性对民主党的支持，但不影响女性。
The last three decades have witnessed the rise of a pohtical gender gap in the United States wherein more women than men favor the Democratic party. We trace this development to the decline in marriage, which we posit has made men richer and women poorer. Data for the United States support this argument. First, there is a strong positive correlation between state divorce prevalence and the political gender gap—higher divorce prevalence reduces support for the Democrats among men but not women. Second, longitudinal data show that following marriage (divorce), women are less (more) likely to support the Democratic party.
