The next time a Republican tries to blame the increasing National Debt on Obama, just mention to them how much the annual interest alone is running on the debt he inherited from all of the past Republican Administrations. The answer? It's close to $0.5 Trillion/year. So given that Obama has been in office for about three years, the national debt could go up $1.5 Trillion and NONE of it would be his fault. One could add in the $1.5 Trillion deficit Bush Jr. left him, as well as the deep recession that he inherited that required many emergency steps ($) to contain. All those would give ample justification for whatever deficits may have/will have resulted on his watch. Too bad the Republicans do not have such justifications for their own gross fiscal mismanagement. Republicans claim they are fiscal conservatives and have great business sense. Too much relevant evidence says no.
