Time to brush up on your math.
The voting gap between men and women tends to range from 4 to 11%; black and white, approximately 80%, but women are only about 4.5X the share of voters that blacks are.
“but women are only about 4.5X the share of voters that blacks are”
You’re not taking into account the demographic trend though. Blacks are a shrinking portion of the population, while women will ALWAYS tend to be around 50% of the population.
