Obama and Mccain's ad

This ad try to show people that Obama is going to work hard and to accomplish his promise as a president.His speech lets me feel more hopeful than Mccain does.In this ad, it shows a lot of expressions that appear from people's face.people smile ,cheer and jump when Obama finish his speech.In contrast, Mccain's ad shows more about his past and try to tell peole he has more experience than Obama.In my opinion,present and future is more important than past. Thus, I feel Obama's ad is better.
