Why do you think Obama won? How do you foresee his policies (both domestic and foreign) during the second term?

The Democrats was won in the historic presidential election in America in 2012. And for a second term leader of the country was re-elected the current President Barack Obama. Based on the opinion of the majority in each of the 50 United States 303 electoral votes were given to Barack Obama and 206 Mitt Romney.

The election campaign in 2012 was the most expensive in the history of the country, the headquarters of both candidates had spent $ 6 billion. (1)
In this essay I would like to look through the main reason of the Obama`s win and his politics; will try to forecast his future steps in both - domestic and foreign policy.
In recent election his 2008 winning coalition (blacks and latinos, women, college educated, and young voters) held up and came out and voted for him again. His campaign team ran a brilliant campaign. They saturated TV with negative ads hitting Mitt Romney all summer as an elitist, rich, untrustworthy, unprincipled, candidate that could not relate to the American people. They hit him hard for his former business career where he took over companies and laid off thousands of workers. They hit him for changing his mind on everything from healthcare, to abortion, to the wars, to climate change. They made him seem untrustworthy and someone that would say anything to be elected.
