Unfortunately, there are too many stupid people in the world to get rid of AIDS/HIV.

Humans are a destructive, violent, warring species who wants as much as they can for themselves, and it would take quite a bit of "motivation" (read: money) to get most countries on the same side.

Also, there will be one nation that would refuse to abide to the agreement to get rid of its nuclear weapons, meaning it would have them to use against the U.S. at any time. This means the U.S. would have to have nukes of their own to retaliate with, or they don't stand a chance. Unless EVERY country in the entire world HONESTLY gets rid of their nukes (unlikely), it's not going to happen.

I fail to see any discrimination in America except some discrimination against whites. If you were to start an all-black club, it's accepted. If you start an all-white club, it's racist. Due to people trying NOT to be seen as racist, they turn out to be discriminatory towards straight white males. There isn't much Obama CAN do to take steps against discrimination, since it's largely under control. If he takes the steps to get rid of discrimination against straight white males, then he would have truly gotten rid of it.

Ah, yes, stopping the Taliban, a group we put together which has stabbed us in the back. This means more military action in Iraq, and, if enlistment keeps declining at its current rate, a draft by 2012. Hopefully I'll be in Canada by then.

Bringing back the economy means putting a cap on gas prices. The puppets of the gas corporations in the congress are going to keep any measure for a gas cap from reaching Mr. President. They have done so in the past, but lowering gas means the truckers will have to pay less to get their goods here, meaning they'll charge the stores less, bringing down prices in those stores, putting more money in everyone's pocket and strengthening the economy. It also means the gas corporations lose their HUGE profits, and they'll keep fighting until the end.

Obama seems like the best choice, better than Hilary, and certainly better than McCain, though his promises are... Unlikely.
