Help me refute my math nerd cousin [View All]

[mysticalchick]

There was a post on FB about who ran up the deficit the most showing Reagan and Bush2 (of course) and my cousin (a usually 'in the background' kind of Catholic republican) posted this under it. I can haz help refuting this please? (Or not, if it's correct.)

"Please excuse the math geek in me but I can't resist a statistic painting an inaccurate picture. Here's the facts from the Wkipedia website: Bush from 2001 - 2008: the public national debt went from $5.8 trillion to $10.0 trillion. That is an increase in $4.2 trillion over 8 years for an average rate of increase 5.25% per year or 42% increase overall. Obama in less than 3 years from 2009 - Feb 2011 took the public debt from $10 trillion to $14.2 trillion for the same $4.2 trillion increase which is 30% increase (building off a higher base) and an average of 9.8% increase per year. If we project the same pace and a second term then we can estimate he would go from $10 trillion to $21.2 trillion which would be an increase of over 50%. I love math. I love facts."

true dat?
