In January of 1993, the total public debt stood at $4.2 trillion. By the end of the year 2000, it stood at $5.7 trillion. So Bill Clinton increased the debt by 35 percent, about 4.4 points per year.
At the end of December in 2008, the debt stood at $10.7 trillion. So George Bush increased the debt by 88 percent, about 11 points per year, a rate 2.5 times higher than Bill Clinton's.
As of August 4, 2011, the debt stands at $14.6 trillion. So Barack Obama has increased the debt by 36 percent . . . in just over one half of one term in office, not two full terms like his predecessors, or 14.4 points per year.
George Bush is clearly a bigger liberal than Bill Clinton, but Obama is already topping him by a rate of 1.3 times.
