Look at the graph, and imagine connecting a straight line from the START of the KENNEDY administration to the END of the CLINTON administration. With minor bumps to either side, the slope of the graph for ALL the administrations in that interval is essentially the same. So, overall, spending increased at about the same rate for ALL these administrations in that time interval. In other words, there was little practical difference in the RATE of growth of the government (as measured by spending) from KENNEDY thru CLINTON.
Then, notice the marked RISE in the slope starting with the BUSH 2 administration, and continued rise thereafter...
Note that Obama is the model of efficiency don’t you know...
