It lumps the Iraq and Afghanistan costs under Bush, is that all the costs for those wars since Obama took office as well?

Does Obama's cost not include the wars he's continued?

The costs for those wars after Obama took office are obviously not included in Bush’s slice of the pie.

Aren't they included in the 1.3 trillion not attributed to stimulus or extension of Bush tax cuts?

… in Bush’s slice of the pie. My comment was misleading, I edited it.

Does it really matter? even if you half Bush junior's chunk you're still more than the 2 last republican president combined. That's incredible. But circumstances are not the same (i'd like to see inflation adjusted numbers for one).

If a CEO had those numbers, shareholders would be suing.

How the debt was acquired?

No.

All this shows is when it was acquired.
