#VoteBike - 2012 London Mayoral elections

And yet in the country as a whole Labour are well ahead of the Tories in the polls and, traditionally, London is more Labour than Tory. The Livingston effect.

We will be stuck with four more years of Johnson because of it. That is why I am angry.

It's less the Livingstone effect than the result of the character assassination of him since the 2008 mayoral election, when he was vilified about a few since largely unsubstantiated charges. (This is not to say that he didn't make mistakes, just that the emotional barrage is out of all proportion to what actually happened.)

It's also the Johnson effect of completely insubstantial politics based on a candidate who for some reason is a very popular entertainer and who, cynically for a Conservative, stood on a platform of 'change'.

Labour's problem isn't Livingstone, but that they don't have a better candidate. Do you really think Oona King would have seriously challenged Johnson in any way?
