I'll take a shot at this.
First, Bush was hardly "chump change." In 2007 the Comptroller of the GAO
estimated that Bush had added $32 trillion to the government's fiscal exposures up to that date, 7 years into his presidency, or about $4.5T per year. When the GAO comes up with comparable numbers about Obama, we can debate who had a higher burn rate.
Second, it all comes down to what constitutes "unnecessary" spending. Bush's spending came from both expansion of entitlements and two discretionary wars. Many (most?) Americans think the second and by far the most expensive of these wars was not only unforced but actually counter-productive -- a net negative for American interests. Obama hasn't done anything remotely like that, yet.
Third, some of Obama's spending (health care) is at least theoretically targeted towards bringing down future costs, and if that happens that actually counts as net savings. We won't know whether that's effective for some time. We do know that Bush's spending didn't reduce any costs -- it is all "dead weight."
So while it's possible Obama may wind up to be a greater spendthrift than Bush, it's far from the certainty you are intoning. As for the "ravishing" of the country, plenty of us are applauding what you might call "ravishing," so don't measure those drapes quite yet. Obama will be re-elected if the economy recovers and dumped if it doesn't. Like a head coach, it's just win, baby.
