The deficit for this year was at $1.2 Trillion on January 7th. (Source: Congressional Budget Office) Which means that ALL of the National debt, except for 500 Billion dollars, occurred under Republican adminstrations, or as a result of interest on the debt from Republican administrations. Of that 500 Billion, 100 Billion is from the Carter administration, and 400 billion is from the stimulus package passed this year. This means that Republican Presidents are responsible for 96% of the National debt... and Obama is responsible for 3% of the national debt, mainly due to a one-time stimulus package that had to be put in place due to the failed Bush economy. So, it seems to me that if you're worried about the National Debt, you should be voting Democrat, for President anyway. Congress is another matter entirely.
