Watch Hillary over the next 6 to 8 months. She is quietly working, traveling, getting the ability to say that she has foreign policy experience, far more than Obama. Except for the Arizona thing she has been quiet on Domestic Polcy, and don't think she didn't let the cat out of the bag on that earlier than the administration wanted because of a blunder on her part, that was a calculated move so that the Arizona Governor and others would have time to get their ducks in a row to give a good fight on this issue, and give time for Obama to get punched around a bit.
Don't think that she is not thinking about running in 2012. She is just waiting, watching, not making any mistakes and in 8 months or so she will test the water in some way to see what it looks like. She already has the Domestic Policy experience, she now is getting the Foreign Policy experience.....if the door opens for her, if Obama's approval rating continues to fall, especially in the Domestic Policy area, don't think for a minute she won't run in 2012. She will also wait and see how a documentary on the 2008 Democratic Primaries and Caucuses goes over to the public.
She's just waiting and watching. IF, IF she doesn't like the climate for her to win in 2012, she will take the VP position, and run in 2016. But, I wouldn't put it past her AT ALL, to run in 2012.
