What was something important Obama did?

By far the most important thing that Obama has done is to push his "Obamacare" health package through Congress. He also ordered his own changes in deportation of illegal immigrants and asked his justice department to sue states that were trying to pass their own laws to stop illegal workers. He ordered justice not to defend the defense of marriage act. He gave gays full rights in the militay and removed restrictions against having women in combat units.
