Americans ARE smart enough, I think, to realize a liberal "government is the answer to every problem" solution isn't the way to go. So while we ought to be concerned about the economy, we needn't panic.
The criticisms of Bush's domestic spending seem to be well-founded, but if that spending is for Homeland Security--and I think much of it is--then I don't have a problem with such an increase. I heard Bush say last year that his NON-DISCRETIONARY, NON-HOMELAND SECURITY increases in budget were around 4%.
Additionally, Bush's tax cuts have increased revenues into the treasury by about $112 Billion. Unfortunately for the budget hawks, most of that will probably go to Katrina Relief; but it is impolitic to say the feds shouldn't help that area rebuild in some ways.
So, there is my 2 cents in this discussion.
