Clinton will certainly, in the end, support her husband's policy.http://firstread.msnbc.msn.com/archive/2007/12/13/514603.aspx#514628Thu, 13 Dec 2007 19:49:22 GMT8a5d2dbc-a0e4-4c7a-979f-3188051f228e:514628BeeObama doesn't need to go after Clinton... I like the way he is staying positive.

OK. We get it.  He wasn't the only one who thougth it was a good idea at the time.  It didn't work.  Hence the whole idea of change.  I find it funny how comments are made regarding HRC's 'swipes' at the other candidates deficiencies, and yet the yet to be elected OBAMA is portrayed as the "better man" for not pointing out weaknesses and points of attack in HRC's comments.  If you don't want the mud slinging, why are you pointing out everywhere you wanted to see it slung?
