@Yellow: all 3 are:
first graph (http://jimcgreevy.com/gvdc/Natl_Debt_Chart.html)
Now lets include the Obama years onto this chart:
2009-1890 (NEW RECORD!)
2010- 1653
2011- 1235
2012 (based on Obama's budget)- 1587
Also I explain below in chart 3 why these numbers are BS.
second graph: http://www.washingtonpost.com/blogs/fact-checker/post/a-bogus-chart-on-obama-and-the-debt-gets-a-new-lease-on-life/2011/09/28/gIQAx40Y6K_blog.html
read the article name BOGUS CHART is the name of the article. And a quote from the article:
"calculated the numbers as if Obama took office a year later than he did."
later on you see the real numbers:
Reagan: 15%
Bush sr: 7.1%
Clinton: -13.4% (Clinton had surpluses)
Bush jr: 5.6%
Obama: 24.6%
So that second site actually goes against you since Obama is the worst of the lot.
Third chart:
According to this chart, under Reagan/Bush, the debt-GDP ratio went from 32.5% to 66.1%.
In reality the debt to GDP ratio went from 26.1% to 48.1%. The other problem with this chart is that it ignores the interest on the debt during the republican years (when balancing a budget, the interest of the debt isn't included. Meaning you could technically have a balanced budget but still see the total debt rise. Clinton is the best example of where this happened, where he had a surplus in his final year, but the debt still grew by $18 Billion.
In fact under his definition of a Balanced budget, the last president to Balance the budget was Ike, who last time I checked was a republican.
In fact under his definition of a balanced budget the budget has only been balanced 3 times in history (Any data before 1935 cannot be defined under his definition). once under a democratic president (Truman) and twice under a republican president (both times being Ike). So his expectation that the republicans could have 16 straight years of budgets which meet a criteria that has only been met 3 times in history is unrealistic.
This chart also makes the mistake of double counting transfer payments (which is a common practice for those wishing to overstate the debt, and your earlier chart (chart 1) also made that mistake (as a result my Obama numbers for chart 1 did this as well).
The last mistake here is the dates the president went into office. The Debt-GDP ratio (again using the double count mistake) the month before Obama assumed office was 69.7% (I don't have data for the exact day, the month before is the closest day I have), the next data point I have is for 85.2%, which judging by their chart is the number they have for change between Obama and Bush. This means they did the same mistake your chart 2 did. Because they had to chose between one month before or 11 months after (and they did the same mistake for the transition between Bush and Clinton) they choose after since it makes their graph look better.
So now I did the calculations using the same method they did except lowering the requirement to consider a balanced budget to what is actually defined as balanced. Had they balanced the budgets during those years the debt to GDP ratio would have gone from 33.4% to 30.2% (using the double count method, to keep consistent with the other graph) during the Reagan and Bush I years, and from 57.3% down to 53.0% in the Bush SR years.
Counting both, rather then one or the other Clinton would have ended with 26.8% and Obama would currently have a 51.5%.
