If women agreed on everything, they could form a 'Woman Party' and rule the US. There are more women in the United States than males, especially of voting age. Why haven't they voted a woman into office yet? Probably for the same reason we haven't voted in a third party candidate - nobody has ever taken a serious run at it.
What I wonder is, will women vote for a woman simply because she is a woman, or will they be more likely to choose based on platform? And, will men vote against a woman simply because she is a woman?
I honestly don't know. I hope I do not have to find out. However, that does not seem likely to me. If a woman runs in the primary, she will probably win the primary. Primaries don't seem to have too many issue debates, because they're from the same party. So, women in her party are more likely to vote for her just because she is a woman, unless something in her platform offends them so badly that they do not.
Last election, my vote may not have counted. This election, I'm pretty sure every state is going to be a swing state. If it's a man vs. woman battle, people are going to be thrown off their normal strides. Also, throw in a third party candidate who believes they can win. They might actually get some electoral votes if they play their cards right.
Now all we have to do is wait for Political Machine: Third Party to come out.
