Johnny Edwards and the Elusive Endorsement

John Edwards is on stage in Grand Rapid, MI endorsing Obama right now. This all happened rather quickly but the message it's sending to the Clinton campaign must be striking. He's even lending his "One America" speech material to Obama during the endorsement.

This is a definite watershed in the race for the nomination as well as the general election indeed. With Edwards lending his fire to Obama the momentum is surely building for the Dems. John McCain who?
