the primary in 2012 if Obama loses, or 2016 (though she'll be a bit old). Even without that though, she is still raised her profile greatly. I suggest this piece, its really good and very friendly towards HRC and all she accomplished in losing: http://nymag.com/news/politics/47837/
some power right now, i think she could literally cost him the election if she says 4 little words to her supporters "dont vote for Obama" Of course, if she wanted a future she would never, but just having that power must have a lot of thoughts racing through Clintons head
blockbuster about this election full of drama and huge rallies. I think it would make a great movie, analyzing the candidates and all, we'll have to wait for at least one book though, we will probably see one by an insider by the end of the year! I cant wait, and your choices are great, i cant do any better. For XMatthews though, id say Phillip Seymour hoffgman maybe?
