In the end, it doesn't matter who will be president. THe USA is on a downward spiral and it will continue that downward spiral. The damage Bush Jr. has done is enough that no matter who is president there will be more attacks on US soil. There will be more hatred and discontent against the US. And yes, we will waste more money and lives on useless endaevors to stop it.
Just because of one little thing, their are certain elements of the US government that can't stop interfering with the policies of other nations. As long as we keep interfering in places we do not belong there will be resentment.
