If it was a coin flip which way men or women might vote, you might have a point. But that's not reality. It's not just one election that didn't go the right way. Women vote the wrong way, every single time, in a completely predictable fashion. Again: Reality is what it is.
Now to be fair, you could largely correct for this problem by restricting the vote to only married women. It's probably not a coincidence that women who are discerning enough to vote the right way are also, by and large, the ones capable of pursuing and maintaining stable marriages. That doesn't change anything else I've said up to this point though.
