Obama's leadership has helped usher in some significant changes, according to the frontman of System of a Down.

“From the healthcare bill to regulation on industries, to key changes in all levels of government personnel and bodies, to the stimulus package, his leadership has done a tremendous job since taking office. The obstructionist opposition in Congress and industry, naturally polarized to all this change, have done our democracy a disservice by acting to block all forms of progress,” Serj Tankian said in an interview with Huffington Post.

“Obama's mistakes are the escalation of the invasion of Afghanistan, and going back on his use of the word Genocide when dealing with the slaughter of Armenians, Greeks, and Assyrians at the hands of the Turks during WWI,” he said.
