I just updated this graph that I posted on some other threads here a few months ago ... about the job approval/disapproval numbers Bush has been getting. It was interesting both to look at the long-term development of the numbers - it looks like a Christmas tree, somebody said - and to compare the results from the different polling agencies with each other.
Basically, Bush got a huge jump after September 11, then started sliding down, until the start of the Iraq war gave him a new, smaller boost. After which he gradually slid down again, until Saddam's capture provided a new mini-boost - after which he slid further down still. There's a distinct trend there <winks>. Going only on this pattern, you'd say only Osama's capture or a new terrorist attack would get Bush to win.
Notable among the polls is that Fox systematically has Bush's
disapproval numbers lower than the other pollsters - and AP/Ipsos and the American Research Group systematically have them higher. With the
approval numbers, it's the ABC/WaPo and University of Pennsylvania polls (and to a lesser extent, those of Fox) that deviate from the average in Bush's favour - and the American Research Group polls (and to a much lesser extent those from Pew and Quinnipiac) that make him look worse off.
With this update, comparing polls has become a little difficult though, because after a long wait, the "christmas tree" has finally gotten its long-awaited star/top! :wink: The "average" graph is very clear on that ...
