This is the best news I’ve read all day. Via tailrank and The New York Times, John Edwards has endorsed Barack Obama’s candidacy! This is big news for several reasons, among them: the “white, working class” vote that Hillary has been bragging about, Edwards’ solid domestic policies, Edwards’ 19 delegates that will likely go to Obama now, and another high profile super delegate going in Obama’s column. This was a coveted endorsement. Great news for the Obama campaign. Next up, Al Gore?
