Presidential Candidates

I have just realized that I do not know enough about the presidential candidates to make an informed decision when it comes time to vote.... I suck. I have been so wrapped up in the kids that the whole world is a blur around me. Time to wake up and see what's going on. Who stands for what? Who do I want running our country? Let's be honest... a republican candidate will not be getting into the White House this year. So... which Democratic candidate am I most impressed with? No clue. I have never like Hillary. But that is a personality thing. I have no idea where she really stands on the issues. And I know next to nothing about Obama or Edwards, either. So... anyone want to give me a heads up? What sites are out there that you would suggest as a way to educate myself without too much confusion? I am an intelligent woman but am out of the loop politically...
