One of the strangest aspects of politics is the way some politicians grab every opportunity to make events fit into their particular worldview. So, when David Blunkett is asked about voting fraud in Birmingham, quick as a flash our Dave is able to translate the question into an answer about the benefits of a national ID card scheme. Equally, when my favourite Lib Dem John Hemming spys a problem "spiralling out of control" at MG Rover, he instantly identifies the DTI (that, coincidentally, the Lib Dems are pledged to abolish) as the main cause of the problem. David... John... the public are not as daft as you perceive, please stop this blatant opportunism and have a bit of respect for them.
