Master Chart of all of Bush's opinion polls pointed out by Fred Wilson. Fortunately, it's a steep downward slope.

I am absolutely stunned by the simplicity and brilliance of this composite graph on Fred Wilson’s site that shows the last four years of opinion polls on George W. Bush. The most informative thing is the amount of trust and faith that has been repeatedly handed to him on 9/11 and then Iraq and then Saddam that has been consistently squandered. I would love to see if these charts have been done for other Presidents or for any of the Prime Ministers of Canada.

A larger version of the graph is here.
