Stadium Seating + Change= Win?

Barack Obama and the DNC has decided to hold Obama's nomination in Mile-High Stadium, home to the Denver Broncos. The stadium hold 75,000, which is monstrous compared to the original venue which would hold 20,000. I mean, the man can pack a house, but 75,000 people. He's officially reached Rockstar status. With the message of change, is this a good direction for politics? Barack Obama has run on the message of change, and it has successfully carried him through the primaries. But how long, will simply the message last in the general campaign? McCain is constantly attacking Barack Obama for not having a firm stance on issues, but is it possible for someone (read McCain) to have too firm of a stance? There's an excitement in this country, and even around the world, in hopes that Barack Obama and his message of change will take the election. I must say personally, that I am extremely excited for the future of this country. But can America take 4 years of McBush policies? To put it bluntly, this country is going to hell in a handbasket, when most of the world hates us, gas costs an arm and a leg, the economy is shit, and Iran telling America to "Just Bring It" if it wants to go to war. We are in dire need of change and I may be the only one who believes that even symbolic change may change the attitudes of this country. Colgate University President, Rebecca Chopp, has said numerous times, somtimes you have to believe in something before you can change your actions. Does America qualify for that type of attitude now?
