Obama speech in Iowa

According to the newspapers, Barack Obama gave a speech that trumped all the others in Iowa. What I've seen so far looks great. He is my choice for the next President of the United States, and he sums up in one fragment how he's different from his competitors (one certain lady in particular):

If we are really serious about winning these elections, Democrats, then we can't live in fear of losing. This Party, the party of Jefferson and Jackson and Roosevelt and Kennedy, has always made the biggest difference in the lives of the American people when we led not by polls, but by principle; not by calculation, but by conviction; when we summoned the entire nation to a common purpose, a higher purpose. And I run for the presidency of the United States of America because that is the party America needs us to be right now. A party that offers not just a difference in policies, but a difference in leadership. A party that focuses not on how to win, but why we should. A party that doesn't just offer change as a slogan, but real, meaningful change, change that America can believe in.

Ladies and gentlemen, I give you the next President of the United States.
