Understood, but single women tend to be more liberal than married women. :)
Interesting statistic but flawed.
Most blacks vote democrat and tend to be liberal. Most black women are single. They vote liberal. This skewers the "single women" vote.
Most black men can not vote for reasons of felony conviction. This tends to skewer the male vote in the other direction.
This produces a flawed result.
When you break it down by race, men and women of the same race, economic and marital status tend to vote along similar lines.
