http://www.addictinginfo.org/2011/04/25/which-partys-presidents-created-the-debt-anyalysis-from-1938-2004/The chart below shows the United Stated national debt (per Microsoft’s Encarta Encyclopedia<1>) with the various Presidents’ terms marked by vertical lines. Under Clinton the growth in debt ceased, but note the radical change in direction debt has taken since George W. Bush entered office. There is no question that the steepest upward rises in debt take place when Conservative Republican Presidents are in office (see red below).
Since 1938 the Democrats have held the White house for 35 years, the Republicans for 31. Over that time the national debt has increased at an average annual rate of 8.9%. The Democratic yearly average (that is the years Democrats were in the White House) was an increase of 8.7%. The years while the Republicans ran the White House, during this same period; the debt increased an average 9.1% per year. Those averages are pretty close.
If you look at the debt starting with Truman’s term (and remove Roosevelt’s WWII debt) the difference between the two parties contributions to our national debt level change considerably. Since 1946 the Democratic Presidents increased the national debt an average of only 3.7% per year when they were in office. The Republican Presidents stay at an average increase of 9.1% per year. Over the last 57 years Republican Presidents have out borrowed Democratic Presidents by more than a two to one ratio. That is, for every dollar a Democratic President has raised the national debt in the past 57 years Republican Presidents have raised the debt by $2.47.
Prior to the Conservative take over of the Republican Party there was not much difference between the two parties debt philosophy, they both worked together to minimize it. However the debt has been on a steady incline ever since the Reagan Presidency. The only exception to the steep increase over the last 23 was during the Clinton Presidency, where he brought spending under control and the debt growth down to almost zero.
