This speech shows a lot of repetition of small phrases. Before that one phrase, "yes we can" Obama gives several examples of things that this country has done that seemed impossible. The whole speech was about the power of America to change and to allow new opportunities to different people. It is true, we have changed. There were slaves before, and now we have a African-American man ready to govern this country. Women couldn't vote, and there were two women in this last election. Obama might have not mentioned these examples, but from what he says it is very clear that he wants to say that in American everything is possible.
Besides this he makes the audience feel a part of this victory. He makes us feel like we have just taken a step towards a brighter future. When He speaks about how his campaign grew.
"It grew strength from the young people who rejected the myth of their generation’s apathy; who left their homes and their families for jobs that offered little pay and less sleep; from the not-so-young people who braved the bitter cold and scorching heat to knock on the doors of perfect strangers; from the millions of Americans who volunteered, and organized, and proved that more than two centuries later, a government of the people, by the people and for the people has not perished from this Earth."
Bitter cold, scorching heat, apathy, has not perished. These give this small paragraph a feeling of hardwork. Obama's appeal to the emotions of the people is present throughout his speech. No one can deny that they felt like screaming as they heard this speech.
