The Democratic Party is one of the two major contemporary political parties in the United States along with the Republican Party.
The Democratic Party has changed significantly during its more than two centuries of existence. During the 19th century the party supported or tolerated slavery, and it opposed civil rights reforms after the Civil War in order to retain the support of Southern voters. By the mid-20th century it had undergone a dramatic ideological realignment and reinvented itself as a party supporting organized labour, the civil rights of minorities, and progressive reform. Since President Franklin D. Roosevelt’s New Deal of the 1930s, the party has also tended to favour greater government intervention in the economy and to oppose government intervention in the private, noneconomic affairs of citizens
Current President of the United States Barack Obama is the 15th Democrat to hold the office of Presidency. As of the 113th Congress following the 2012 elections, the Democratic Party currently holds a minority of seats in the House of Representatives and a majority of seats in the Senate, as well as a minority of state governorships and control of a minority of state legislatures.
