What Are The Rhetorical Devices In Obama's Convention Speech

Before his speech in Democratic National Convention Barac Obama was unknown to most people, therefor his convention speech gave him a chance to introduce himself to people as someone new and dynamic. Obama's speech was so effective due to his ability to talk to large groups of people. He uses lots of antithesis and repetition as a device in his speech.

Obama tells about his family history as a part of a greater American story, and gives large groups of people change to identify with him. His message is that Although Americans regard individuality very high, they are all connected as a one people. He reminds people about the things that people, who are often divided to separate groups, for example by political party or etnicity, have in common.
