in the words of my nine-year old son, "that is a general statement." in my words, "hardly a rational statement."
It is, but it is accurate and consistent with psychological findings. Women do tend to make decisions about how they "feel" rather than what they "think". Usually that makes everybody, especially children, gain instant happiness and gratification; but, rarely does it suit long-term needs.
Women are perfectly capable of rational thought, but vote more like in a popularity contest. They vote for pretense of short-term security, not long-term sustenance.
