When compared to the Republican majorities of the prior 12 Fiscal Years (FY 1996-2007), Democrat Majorities in the last 5 Fiscal Years (FY 2008-2012) have More than QUADRUPLED annual increases to the Total National Debt!
All appropriations (spending) bills must be passed by the U.S. House of Representatives, passed by the U.S. Senate, and signed by the President of the United States (unless a Presidential veto is overridden with 2/3 majorities in both the House and Senate).
I think it is fair to give the majority of the credit and/or blame to the party which controlled a majority (2+ out of 3) of those three entities.
Bill Clinton began his Presidency with a Democrat House and a Democrat Senate. But in his first mid-term elections, in November 1994, Republicans won control of both the House and Senate for the first time since the election of 1946. It was a big deal. And based on the election results of 1994, 1996, 1998, 2000, 2002, and 2004, Republicans earned control of both houses of Congress for 12 straight years. Democrats managed to take back control of the Senate during the 107th Congress when RINO (Republican In Name Only) Jim Jeffords switched from Republican to Independent and caucused with Democrats. Still, during that time, George W. Bush was President, so even though Democrats controlled the Senate, Republicans controlled the House and Presidency, and therefore a majority of the three budget-making bodies.
The Republican House and Senate candidates who were elected in the November 1994 elections took office on January 3, 1995. The Fiscal Year 1995 budget was already in place. So, the first budget that was passed by a Republican House and Republican Senate, and signed by President Clinton, was the Fiscal Year 1996 budget.
A Republican Majority was responsible for Fiscal Years 1996-2007.
In the November 2006 elections, Democrats took back control of both the House and Senate, and therefore majority control of the budgeting and appropriations process, even though George W. Bush was still President.
A Democrat Majority was responsible for Fiscal Years 2008-2012. And during those years, Democrats have More than QUADRUPLED the annual increases to the Total National Debt.
Compare the Total National Debt on the last day of the relevant Fiscal Years. The last business day of FY 1995 was 09/29/1995, and according to http://www.treasurydirect.gov/govt/reports/pd/histdebt/histdebt_histo4.htm, the Total National Debt was just under $5 Trillion:
After 12 consecutive years of majority Republican control of the budgeting and spending process, on the last business day of Fiscal Year 2007, according to http://www.treasurydirect.gov/govt/reports/pd/histdebt/histdebt_histo5.htm the Total National Debt was just over $9 Trillion:
Republican majorities added $4,033,670,471,553.09 (over $4 Trillion) to the Total National Debt over the course of 12 years.
On average, Republican majorities increased the Total National Debt by $336,139,205,962.76 ($336 Billion) per year.
We have now had five consecutive years of Democrats holding majority control of the budgeting and spending process. The last business day of Fiscal Year 2012 was Friday 09/28/2012, and according to http://www.treasurydirect.gov/NP/BPDLogin?application=np the Total National Debt on that day was over $16 Trillion:
Democrat majorities added $7,058,588,035,123.41 (over $7 Trillion) to the Total National Debt over the course of just 5 years.
On average, Democrat majorities increased the Total National Debt by $1,411,717,607,024.68 ($1,412 Billion a.k.a $1.412 TRILLION) per year.
Democrat Average / Republican Average =
$1,411,717,607,024.68 / $336,139,205,962.76 = 4.1998 = 419.98%
Democrat Average over the last 5 Fiscal Years has been 4.2 times as much as (i.e., 420% of) the Republican Average over the prior 12 Fiscal Years!
Democrats have More than QUADRUPLED the annual increases to our Total National Debt.
