Non sequitur: president's speech and confidence!

So, our President is scheduled, again, to talk to the country (and the world) about there being no need to panic, and to restore confidence.

I can't see his speech doing anything; in fact, there is a good chance that the market will tank further after his speech. Why?

The latest polling data show that the gap between his disapproval rating and approval rating is the widest ever among all the presidents. Wider than Nixon at his worst. Seriously, you think he can restore any confidence in anybody?

Here is "Countdown to Crawford":

President Bush is nearing what may be a new distinction: an historic 45-point spread between the voters who give his performance a thumbs down and those who are still giving him a thumbs up.
Though this may be an arcane calculation, it's interesting to ponder.
At one moment in his presidency, Richard Nixon registered 66% disapproval rating from voters, against a 24% approval, for a 42-point differential.
Harry Truman, often derided by critics, experienced a range of 43 points between the disapproval and approval numbers.
Santi Tafarella, who blogs at Prometheus Unbound, looked at years of the numbers from the Gallup Poll and concluded that George W. Bush has passed Nixon and Truman to become the president with the widest spread.
As is apparent from the Roper Center for Public Opinion Research's chart above, at the moment, the president's disapproval ratings are at 70%, while only 25% gave him positive marks. Which would give him an historic margin of 45 points.
