So, what exactly is the truth value of Bush's prediction that he would be a uniter and not a divider?

There's a good reason we don't often post poll numbers a lot, but I want to make one exception. The new CBS poll on the Iraq war records that:

CBS Poll: 76% Say War's Going Badly, Record Number In Survey Say Getting Involved In Iraq Was Mistake - CBS News: "a CBS News/New York Times poll shows the number of Americans who say the war is going badly has reached a new high, rising 10 percent this month to 76 percent. "

But the really really interesting poll number is buried a bit in the article:

In addition, the poll finds Americans are more pessimistic than ever about the overall direction in which the United States is headed. Seventy-two percent, the highest number since the CBS/NYT poll started asking the question in 1983, say the country is on the wrong track, while 24 percent say it's headed in the right direction.
