Is the bottom falling out?

I've referred to this poll, Pollkatz, in previous posts. It summarizes and charts, with fine graphics, the numerous polls on numerous issues.

The "Bush index" is a definitive polling indicator, because it measures the spread between Bush's approval and disapproval numbers, as determined weekly by averaging the polls concluded during that week.

Well, as you can see, the news ain't good for Bush, not at all. Pollkatz's figures reveal the highest spread ever between those figures--24.2--whereas no previous index had risen above 20. This means, according to the broad sample of polls, 36% of Americans approve of Bush's handling of his presidency, and 60% do not.

A "silent majority" has arisen, to be sure. And it's a big majority, growing bigger by the week.
