Gore Endorsed Obama: Big Deal

So, Al Gore finally endorsed Obama: Wahat a colassal surprise! Really, who was he going to endorse, McCain? There is nobody left to make a choice about except Obama! Would have been nice, and when it mattered to have endorsed earlier. No surprise though, this is Gore we're talking about. He has no backbone! And why is everyone acting like he's the prodigal son? The manb had a sure thing in 2000 and f---d it up because he was too holier than thou to ask for Bill Clinton's help to elect him because of the Monica scandal. Even so, he lost Tennessee and Arkansas, which had he won both, he would have been President. I see no benefit to the endorsement now... what is it supposed to do for Obama? Maybe win Michigan, which McCain is now leading? From what I'm hearing, Michigan is none too happy with Gore so what is the point of doing it there or at all?
