Congressional Budget Office - A Preliminary Analysis of the President's Budget and an Update of CBO's Budget and Economic Outlook
Bush's deficits for publicly held debt is $2 trillion, while debt held by public increased by $2.4 trillion. I'm pretty sure you just checked the Heritage site without making sure their computations were correct. And I'm pretty sure the CBO data is not inflation pegged. So Bush's deficits are actually significently more than that $2 trillion. Especially since the debt also increased on government held internal debt.
The number is not worse. Last I checked, $1.8 trillion < $2 trillion (actually more, but I'm too lazy to inflation peg each deficit).If you deny that it IS worse, you're simply delusional.
It is worse as a whole for the nation because Bush's debt accumulation was real bad. Now we're piling on even more.
So technically, you are wrong.
