It’s VERY SIMPLE. Married women usually have kids - they have a reason to vote to NOT DESTROY our country.
Single women, at least in this context, simply hate men and vote to screw over men, which means they vote Democrat.
So I’d say the MORE IMPORTANT question is why do single women vote to destroy this country, when the vast majority of them, even if they have no kids, have relatives that they love who do have kids? It’s not for economic reasons, as they generally made decent money...so maybe the answer is as I stated above?
(obviously I’m generalizing here...and there are plenty of conservative, America-loving, single women - just not the majority)
. . . half of whom are boys whose future depends on the status (including fatherhood, upon which their mothers grand-motherhood will depend) society attributes to men.
