Women as a species should not have the franchise - period. I have an educated wife (Masters level) and 2 daughters with graduated degrees and 1 son. I know the territory, have observed voting habits for 60+ years.
I know that this is tongue in cheek. However it cannot be denied that U.S. Politics began to take a sharp turn towards the vulgar modern welfare state immediately following women getting the right to vote. This is a historical fact. You could argue that this would have happened anyway. I am not sure. I think that this is an interesting subject.
