Obama is popular. The people seem to want him. Everyone is rallying around him. He is uniting people of different socioeconomic demographics on one claim . . . change. He is bringing in record amounts of money from fundraising and he is doing it with out PACS. It seems that even Clinton can not contain this movement. People are desperate for "change" and they are counting on Obama to fulfill it. It isn't that Clinton is not qualified because I think she is more qualified as an individual but its that he can organize and surround himself with individuals that counter any weaknesses.
Obama has branded himself well and he has a loyal support from individuals in the arts community that intend to promote his message, voluntarily mind you. This last video is a showcase that individuals are serious about change and they will do all they can to spread the message.
What does this mean? It means that Obama will be the Democratic candidate. After reviewing poll numbers in Texas and Ohio, it is quite evident that Obama may win but more importantly if Clinton wins, she will only so by squeaking by. A win is not sufficient for Clinton, she must blow Obama out and it is unlikely that she will. That means that she will end up splitting the delegates and fail to put a damper in Obama's delegate lead.
You may claim that you knew Obama would win, so what now? This is when it gets tough. Obama nor Clinton will garner the necessary minimum delegates needed to secure the nomination in the Denver Convention. It will then come to the Super Delegates to cast the deciding vote. As insiders, they will give the win to Clinton and undermine the peoples choice of Obama. This will shatter party loyalty for the perceived goal of achieving change. The voters will not turn out for Clinton. This makes it tough for Clinton since she would never want to undermine the party's goals of winning in 08 just so she can win the nomination.
Clinton will have to withdraw as the convention nears. The only reason she may not is if she has a lead in the delegate count but nonetheless . . . support will not be there as it was for Obama. At the end of the day, Obama will be the nominee. If he is not, voters will see it as a slap in the face of their choice and the Democrats may end up losing more then the election at the end of 2008.
