From twelve time zones away, it looks as if the United States is in one of those moments where the capacity to get serious and face big problems is sorely tested.

In the short term, a worldwide financial panic and crisis. Just beyond that, the real economic and social problems that come when large numbers of people lose their jobs, their businesses, their investments, their homes, and even larger numbers become fearful about what might happen to them. And then, when we get a minute to think, profound global energy and environmental challenges, security concerns that range from loose nukes to terrorist organizations, plus a couple of ongoing wars and ever-rising medical costs. Just as starters. The United States is still incredibly rich, powerful, and productive. But the current situation is no joke, for America or the world.

In these circumstances, and with a presidential election four weeks away, is it conceivable that candidates will waste time arguing whether one of them has been in the same room with a guy who had been a violent extremist at a time before most of today's U.S. citizens were even born? (William Ayres was a Weatherman in the late 1960s. Today's median-aged American was born around 1972.) Of course, it's not only conceivable: it's the Republican plan for this final push -- "turning the page" on economic concerns and getting to these "character" and "association" questions about Barack Obama.
