What did Barack Obama do that was of significance?

Answer 1

This calls for an opinion, so please be courteous. In addition to becoming the first black president in US history and the first born in Hawaii, President Obama's supporters would mention a number of significant achievements. They would say he rescued the US economy from an impending depression, helped the US auto industry to recover, brought the troops home from Iraq, expanded health care access for millions of Americans, and supervised the mission that brought Osama bin Laden to justice.
