All my adult life, I've seen politicians talking about addressing problems in our country, but never do they talk about taking on the root cause of those problems. For me, the difference between Obama and every other serious contender for the presidency during my adult life is pretty simple. Everyone else talks about fixing problems through a broken political system; Obama talks about changing the system. It makes sense really; if you're job is to be a politician, then you're employed by the system. This speech moved me to tears. Yes, it's half an hour long, but it's required listening (you don't have to stare at the screen) for anyone voting in this election.
