The Voters, Damn Them, Refute the Tory Right
At the risk of careering round an old argument, Jonathan, the graphs you've produced on political affiliations are yet another reminder, if ever one were needed (and it is) that the Tory right's argument that Cameron would have won a majority if only he'd run a blue-meat campaign is dreadfully mistaken. As you can see, more voters identify with the left than the right. This was Tony Blair's legacy and the ground upon which Cameron was compelled to fight. I suppose it is possible that Cameron could move right without alienating voters who consider themselves - accurately or not - centrists but I suggest this is not probable.
