that my interest a lot. While Obama has won the primaries, there is still a vote in August by the democratic delegates to choose who will run, hence the reason why Hilary has not conceded defeat. If she concedes then there will be no need to vote in august if she doesn't then the party will have to vote. The primaries according to what i have read are also known as the popular vote, it is how the party gauges who will get them the most votes come election, this with the vote in august will determine who gets to go on, so hilirary providing that she wins the majority vote from the delegates could still end up the democrates main candidate.
