The rumor mill is a buzz with a rumor that former presidential candidate John Edwards will endorse Barack Obama this evening at a rally in Michigan.  Rumor confirmed.  AP is reporting that Edwards has endorsed Barack Obama.  The Obama campaign also announced that there will be a “major national endorsement” tonight at 7pm.  Further, Edwards said a couple of days ago that he would be endorsing the person that he voted for in his North Carolina primary very soon.  Edwards has also been dropping other hints in the last few days by criticising Clinton for her comments about the “white vote.”  Edwards also said that he cannot figure out how Clinton could ever win.  I guess now would be as good a time as any seeing that Obama is about to clinch the nomination next week.  My question is will Edwards ask his his pledge delegates to vote for Obama at the convention?  I believe that he may still have between 8 and 13 pledged delegates.  Edwards actually won 18 pledged delegates some of which have already been reallocated.  Edwards can strongly urge his pledged delegates to support Obama but the delegates can now vote for whomever they please.
