I've spent a fair amount of time over the past few months following the Presidential elections in the US, and you can tell from the links at the side where my political persuasions lie, but it is always good to hear both sides of the story. One of the BBC's 'Have your say' sections at the moment is 'Can Kerry Beat Bush?' Of the comments from Bush supporters, one is typical of many that I have heard:

Our country hasn't been attacked on our soil since Bush had the spine to address the terrorists and take the fight to them.

Or to put it another way, in the 3 years since 9/11, the Bush administration's policies have prevented another terrorist attack. I'm a smoker, have been for more than 3 years, but I don't have cancer - does that mean that smoking prevents cancer?
