EXPLANATIONS BELOW
Concept note-1: -Obama signed many landmark bills into law during his first two years in office. The main reforms include: the Affordable Care Act, sometimes referred to as “the ACA” or “Obamacare", the Dodd–Frank Wall Street Reform and Consumer Protection Act, and the Don’t Ask, Don’t Tell Repeal Act of 2010.
Concept note-2: -However, due to a close race between Obama and Senator Hillary Clinton of New York, the contest remained competitive for longer than expected, and neither candidate received enough pledged delegates from state primaries and caucuses to achieve a majority, without endorsements from unpledged delegates (superdelegates).
