Obama clinches Democratic nomination

Obama clinches Democratic nomination, by sarah hallman

"Senator Barack Obama has claimed the Democratic presidential nomination, prevailing through an epic battle with Senator Hillary Rodham Clinton"

It was announced that Obama has finally won the place of democratic candidate. The question I wish to ask though is, after all the fighting that occurred for this to happen is it even going to be worth it? The Democratic party is divided, how are we supposed to unite and win after fighting against each other for so long? Will we able to pull it together or will McCain win the election and make everything that has been done pointless?
I fear that it will be the latter.
