We need the change

The collapse of the Soviet Union changed the world order since WW II. And at the end of the Cold War, the world political structure turned from a bipolar to a unipolar superpower status. The United States became a leader of the world and no any other country can contend with it. However, with the recovery of Russia and the rising of China and India, there is something gonna happen to change the unipolar world.

It's obvious that Barack Obama's position is adapting the new trend, which is a wise choice. Anyone who tries to go against the trend of the world is doomed to fail.

Energy.The energy is limited though abundant. So developing renewable energy is crucial. John McCain's "drilling policy" is not a good way to solve the problem because it will not only consume the only resource we have but also bring about environmental problem.
Education.School vouchers put public school in a disadvantageous position due to the lack of money and it's not good for the working class. Another possible result it may lead to is that all kinds of "bad" students go to the public school because private schools become more selective with more applicants, which may lead to the abortion of public school and lapse of universal education. Obama's position concerned more about the working class and is for the fair of the society.
Marijuana.Limited use of Marijuana is necessary unless there's a better way to reveal the pain of people. It's quite humane. And it's important to "give first-time, non-violent offenders a chance to serve their sentence, where appropriate, in the type of drug rehabilitation programs" to let them know that they can still have a good life if they change rather than letting them feel they've abandoned, which may result in worse consequences.
China.Of course it's important to at least keep the trade agreements with China because it's somehing mutual-benificial--that's a good deal. And the reducing of US debt by China is reasonable because decline in the dollar exchange rate causes large amount of foreign exchange reserves owned by China evaporated alomost over a night. And the devolopment of China is beneficial to the United States and the whole world. On the contrary, John McCain wants to streghten the already powerful US army, which can only make China and Russia upset, which is not good for the peace of the world and is also against China's Harmonious World idea.

We need the change so we need Obama!
