America needs change.

Armed with firmness,Obama didn't smile even when the audience supported him with thunderous applause and cheering during the speech of"Change We Need" on September 16,2008.If I'm an American citzen, I'll no doubt vote for him in the belief that he is decisive, brave, and practical.
Whether a candidate will be a good president depends on what he has done and will do instesd of what he has boasted about. In terms of energy, McCain wants to look at more nuclear possibilities while Obama has set clear goals about "phasing out the incandescent lght bulbs ". What big difference! Besides, when I surf on the internet ,I can easily find the Obama official website, whereas the McCain official website hasn't turned up to me yet! These small things can fully convince a girl as sensitive as me of his greater ability to be a president.
As an African-American, he was brought up knowing how important a role the hierarchy has played in today's social life and what the people from the middle class and even lower class need most. He must find himself a fish out of water surrouded by white men in politics.He comes from the difficulty,and has already had the achievement . America is in the difficulty,and will go to success by his firm leadership.
In fact, let's look at McCain's position.The idea that the millitary can play a role in influencing the current rise of China and Russia and promoting America's economy is woefully mistaken.Though the economy in China is indeed growing fast , it is still a developing country.Believing harmony the best policy from ancient times, will China be so sadly naive as to attack other countries instead of developing its own economy?.Look what practical things Obama has suggested. Though reducing the amount of debt held by Beijing may cause dissatisfication of China, the fact is that if America cannot recover from the economy depression, the whole world's economy will be affected .Obama has the courage to protect America's own interest and he will do it!
