Look at the graph. Clearly Bush Junior was trying his hardest in the first term to reduce the debt. And luckily the intelligent American people realized that Bush needed another term to rescue America's financial situation. The American people are so smart, if only they had elected him for a third term. Imagine if every single citizen in the world was as smart as the average American citizen. The world would be a much better place!
Anyway, easy way to debunk this bs-thread is to look at the area between the curve and the x-axis. Democrats have clearly less deficit spending if you look at the first chart (considerable amount nevertheless). Clinton even managed to rise US to savings from huge deficit which was left after Reagan and Bush I. Bush II managed to plunge the deficit back to the pre-Clinton levels. Republicans have bad habit starting wars and that explains a lot. % of something charts are not difficult to read.
