Move The Bush W George
I believe the major area of focus will be on cleaning up the Iraq and Afghanistan conflicts. There are also some Supreme Court justices that need replacing for health or age reasons, and that will take up some time and energy. There will be healthcare issues, tax issues, and the normal economy/jobs/oil prices issues. And of course the Israel/Palestine situation. With Arafat ill... the possibility of his death is a new problem, and there is no telling what the Palestinian Authority or Hamas will do.
In short, there are plenty of on-going issues that need resolution, and Bush has only 4 years to take care of it all.
In my opinion, of course.
