"From 1962-2001, the average growth in total federal spending under Republican presidents has been 7.57%; under Democrats, 6.96%. Bush certainly did not help those averages any after 2001. During that same period, the average yearly deficit under Democrats was $36 billion; the average under Republicans was $190 billion.
