I don't think women vote as a monolithic entity, and I don't think anyone serious thinks so either. (I'll ignore the people whose lives revolve around the political blogs and/or talk radio/Air America). There is no such thing as "the women's vote".
I don't think there is a monolithic voting entity of any kind, particularly on the national or state-wide levels. Certainly the 'media' like to use terms like 'black' vote, or 'womens' vote, or red states vs blue states. It's rather unfortunate in a nation which prides itself on individuality.
Perhaps it's a reflection of a two party system, well there are others like Libertarian, Independent, Green, . . . , but the system is dominated by two parties, as opposed to mutliple parties as is the case in many other countries.
Many individuals do vote for simple reasons. I've mentioned it before, that I encountered a woman who voted for GW because he was better looking than Kerry. She also mentioned, she did not understand the issues, nor was she inclined to expend any effort to understand the issues, e.g. tax policy, international relations, etc.
There is a big difference between those who keep their religiosity personal and those who are compelled to impose their religiosity on others or advertise it conspicuously. The latter is inclined to use the government to impose their particular religious ideology on the mass population, e.g. by introducing or promoting prayer in school, or creationism/ID in science curricula, or using public funds to financial support particular religious groups and exclude others, . . . .
