I am very much decided but my husband is not. The undecideds I know fall into two camps:
1. Historically democrat but not happy with Obama. They could have been easily swayed to vote republican but they don't like Mitt Romney and/or the social platforms of the republican party. (e.g. gay marriage, abortion, religion etc.)
2. Historically republican but don't like Mitt Romney or religion in government.
I think a lot of the undecideds aren't waiting to hear anything. They just don't love either candidate and they're trying to choose the lesser of two evils.
