Great opinion piece at the Wall Street Journal by our good friend Thomas Frank:

Last week, Republican presidential candidate John McCain called for a commission to “find out what went wrong” on Wall Street. It was an excellent suggestion: Public inquiries into Wall Street practices served the country well in the 1930s.

And Mr. McCain has a special advantage to bring to any such investigation — many of the relevant witnesses are friends or colleagues of his. In fact, he can probably get to the bottom of the whole mess just by cross-examining the people riding on his campaign bus. So the candidate should take a deep breath, remind himself that the country comes first, pull the Straight Talk Express over at a rest stop, whistle up his media pals, and begin.

Topic A should be deregulation. Financial institutions are dropping everywhere after playing with poorly regulated financial instruments; the last investment banks standing are begging the government for stricter oversight; and some of our nation’s leading champions of laissez faire have ditched that theory in an extraordinary attempt to rescue the collapsing industry.

The philosophy of government that has dominated Washington for almost three decades is now in ruins, and it is up to Mr. McCain to find out exactly why we believed it in the first place.

By the way, the polls suggest voters agree with Frank.

“More voters trust Obama to deal with the economy, and he currently has a big edge as the candidate who is more in tune with the economic problems Americans now face. He also has a double-digit advantage on handling the current problems on Wall Street, and as a result, there has been a rise in his overall support. The poll found that, among likely voters, Obama now leads McCain by 52 percent to 43 percent. Two weeks ago, in the days immediately following the Republican National Convention, the race was essentially even, with McCain at 49 percent and Obama at 47 percent. “
