Obama

Obama at 1.9 Trillion and counting... counting because the Timmy "the Elf" Gheitner is asking to increase the budget.

You should clarify between "spending" and "wasting."

By far, Bush jr and Reagan have wasted more taxpayer dollars than all others combined.

So far: Bush - with nothing to show for it, unless you own Haliburton shares.
