If you track Presidential races since 1918 when women got the vote, not one single Democrat president would have gotten into office without the women’s vote carrying him over the top. We got FDR, the New Deal, Social Security, and a mammoth, debt-ridden government because of the women’s vote.
Democrats would have been elected President. But they would have adjusted their policies to please the all-male voting base. Both major parties have continually adjusted their policies to changing demographics and changing times.
