How Ken can win
Here's a few stats which show what a difference good local campaigns make, as well as the task facing Ken in defeating Boris in the London Mayoral elections in 2012.
I've looked at five London constituencies which Ken lost in 2008, and which were close fights in the General Election in 2010 Labour and the Tories. In some of these, Labour ran weak local campaigns with poor candidates, in others, they ran strong local campaigns with excellent candidates.
Across London, Boris led Ken by 44% to 37% in 2008.
In both Brentford & Isleworth and Harrow East, the Labour candidates had received a lot of criticism over their expenses.
In Brentford & Isleworth, Boris beat Ken by 44% to 37% (identical to the results across London as a whole), whereas in 2010 the Tories beat Labour by 37% to 34%.
In Harrow East, Boris beat Ken by 49% to 36%, whereas in 2010 the Tories beat Labour by 45% to 38%.
In both cases, Labour closed the gap between 2008 and 2010, but a similar performance across London in 2012 would see Boris narrowly re-elected. However, the picture is very different if you look at three other marginal constituencies.
In Ealing North, Boris beat Ken by 41% to 39%. In 2010, Steve Pound crushed his Tory opponent 50% to 30%.
In Hammersmith, Boris beat Ken 41% to 40%. In 2010, Andy Slaughter saw off a well funded Tory campaign by 44% to 36%.
In Westminster North, Boris beat Ken by 46% to 38%. But in 2010 Karen Buck beat one of David Cameron's personal friends by 44% to 39%.
Andy Slaughter, Karen Buck and Steve Pound all backed Ken as Labour's candidate for Mayor. If Labour can learn and replicate the secrets of their successful campaigns across London, Ken will be back in City Hall in time for the 2012 Olympics.
