All things considered, Bush is legally our president within the bounds of the law. It went to the Supreme Court. The law was used to its full extent. If anything happened now, it would be grandfathering the current laws. That could be a problem.
Laws can change, but it takes time.
Eventually it will become second nature to think of George W. Bush as the president, perhaps a few months. Conflicts usually die down. He will do his presidential duties, and politicians and the media will praise and criticize him for it. We have a nice system of checks and balances. This is the nature of things.
