Maybe it's a geography thing - in my part of London the Olympics is seen on balance as a good thing - it's creating jobs (construction, engineering) in an area of relatively high unemployment and basically people will look forward to it. There are issues, certainly (VIP lanes etc). But whereas it should be Cameron on the back foot explaning why he's wrecking the NHS, instead it's the unions. The sky hasn't fallen in but he just helped Cameron get out of a spot, when he should have been intensifying the pressure.
Of course what happens in terms of the media agenda doesn't *determine* people's political outlook - but it does influence it. - so avoidable mistakes are best avoided.
