Kerry endorses... Obama?

John Kerry lost the '04 Presidential Election, but maybe he will turn out to be a big infuence in this race. Not only did Kerry chose Obama over his '04 running mate, but he did so in South Carolina, home of the next primary, and also the birthplace of John Edwards. However, this might not have been a shock to Edwards, who criticized Kerry's campaign in '04. Naturally, this should give Obama some more support, but how does this affect the Clinton campaign? Can this be seen as Kerry insulting both Edwards and Clinton? CNN's article about this story, found here, says Kerry's email will send out notices to millions of Kerry supporters. Maybe this will even hurt McCain, and move more Independant voters into Obama's camp. Although I doubt it, if Edwards does feel bitter about this, he might choose Clinton over Obama, likely giving her the nomination. Any way you look at it, this can have a lot of different effects on the race.
