Ratio of Democrats to Republicans in the Federal Government

There are 242 Republicans in the 112th Congress House of Representatives. This is the most Republicans in the House since 1949, but this is not the high point of Republican power in the Federal Government. During the 108th and 109th Congresses (2003-2007) Republicans had a majority in the House and Senate, as well as holding the Presidency. 

The following chart shows the ratio of Democrats in the Federal Government since 1957. A value of 1 would imply that the President and all members of Congress are Democrats. A value of 0 would imply that all are Republicans. Values are weighted with the assumption that 50% of the power lies in the Presidency, 25% in the Senate and 25% in the House of Representatives. Independents and members of third parties were ignored by excluding them from the total number of members in the respective body. The high point of Democratic power (since 1957) was the 89th Congress (1965-1967).
