Election Ads

I feel these two ads are totally different. Obama's ad makes me feel happy and easy, he let me feel Americans need to look forward and do better in the future. I think Obama can let Americans change to better and do not live in the past. I don't like McCain's ad, because the feeling likes nervous and a little bit sad. I know he suggest security and let Americans safe. However, he makes the feeling too strong which is like if we do not have the stronger Army or protection systerm( security), we are in dangerous tomorrow. McCain give Americans too pressures.
