Sudden moment of clarity
I've spent this morning puzzling over why a bigger issue in the London Mayoral election hasn't been the incredible fact that the candidate leading in the polls has so little political commitment to London that he represents Henley, Oxfordshire, in Parliament.
Why isn't this a deal breaker?
For instance, if an MP for a Manchester seat ran for First Minister of Scotland because they had a holiday home in St Andrews, or an MP for Leicester ran for Elected Mayor of Stoke-on-Trent because they were on the electoral register there, there would be an outcry.
Why aren't voters asking Boris the obvious question: "why should we believe you care about our city when you have pursued your political career in the rural Thames Valley?"
