While that's fun and inspirational for the short attention-span crowd, here's the real speech (it kicks in around the 2 minute mark). It's very compelling - in that rather vague hope/change sort of way. Obama's a blah debater, but an amazing speaker. But at the risk of sounding like a total drag, I'll quote one of my favorite Slate journalists and fellow Obama supporter, David Plotz: "I don't want to be rallied." He went on to say that the nature of crowds can be scary - they have a tendency to act "independently of rationality." Plotz goes so far as to call it rather "fascistic," which isn't necessarily as far-flung as it sounds. Obviously, Obama is not a right wing fascist, but the massive rallying of large groups of people can be both amazing and dangerous: "mob mentality."
It's hard not to be swept up in Obama's promise of hope and change in these extraordinarily frustrating times when, as a citizen, you feel hopeless, impotent and cast aside... but just remember to think for yourself and remain a healthy skeptic of those who lead this country - because it's your freaking country, too.
