I have been waiting on this article about this sudden McCain about-face: McCain Embraces Regulation After Many Years of Opposition

From The Washington Post:

A decade ago, Sen. John McCain embraced legislation to broadly deregulate the banking and insurance industries, helping to sweep aside a thicket of rules established over decades in favor of a less restricted financial marketplace that proponents said would result in greater economic growth.

Now, as the Bush administration scrambles to prevent the collapse of the American International Group (AIG), the nation's largest insurance company, and stabilize a tumultuous Wall Street, the Republican presidential nominee is scrambling to recast himself as a champion of regulation to end "reckless conduct, corruption and unbridled greed" on Wall Street.

McCain hopes to tap into anger among voters who are looking for someone to blame for the economic meltdown that threatens their home values, bank accounts and 401(k) plans. But his past support of congressional deregulation efforts and his arguments against "government interference" in the free market by federal, state and local officials have given Sen. Barack Obama an opening to press the advantage Democrats traditionally have in times of economic trouble.
