Perry's speech yesterday spoke to that very issue, suggesting that no one is perfect, and that forgiveness is what makes people of faith stand out. He said this while endorsing Newt. It was powerful.
I know several conservative women. Every single one of them including at least 2 *gasp* who are single mothers (the very kind that people would have us believe would hate Newt) are supporting him because he will spank Obama and take back this country.
