You may want to brush up on your history a bit.
If you're interested in what Bush really did instead of what his handlers said he did, visit my FR home page.
Bottom line: Bush's economic policies caused the real estate crash.

Sorry, I don't know why this link may not work.
I do know that President Bush did not order banks to begin issuing sub-prime mortgages. The actual practice began during the Clinton years.
Many bankers were heeding Bush/Greenspan warnings to curtail sub primes, when democrat operators in the FDIC threatened them with audits, and investigation (publicly calling them racists) if they did. What I have found is there are as many opinions about the cause of the financial crash of '06 as there are defunct banks, but in no way can it all be placed on the shoulders of George W. Bush.
