"... the only thing fueling his economy was a booming housing market and stock market turning turning toxic mortgages into derivatives..."
This is, of course, nonsense. The health care, oil and gas exploration, and mining sectors all grew strongly under the Bush administration, as did chemicals, fertilizers, and electronic goods.
The stock market produces virtually nothing to help the economy, either good or bad.
The toxic mortgages were primarily the result of Clinton administration policies, although the Bush administration perpetuated some of them (certainly not all).
