Boris Johnson: why he shouldn't vote Conservative

From a teasing morsel I produced for Cif the other day: I gaze at Labour's newly minted general election document for London, its 16 pages of fine if fairly insubstantial talk about fairness and investment and a past 13 years of perfect fabulousness, and I think of the capital's Conservative mayor. If he took a look what would he see? Here's the very first pledge: Support London's economy to secure the recovery and promote growth and jobs, including vital infrastructure projects such as Crossrail. Further down the same page comes a promise to "complete the Crossrail project", the huge new west-to-east rail link that will vastly increase the capital's public transport capacity. Ingrained though his disdain for all things "socialist" might be, that fine blond head would surely nod in involuntary approval. Compare the Labour undertaking with shadow minister for London Justine Greening telling LBC radio: "I can't give a guarantee that it will continue." Boris has been using every power at his disposal to raise cash for Crossrail and badgering the Labour government for assurances. Now he has received one, yet his own party cannot match it. Cripes. The rest of my piece is here . We might add to it a further reason for Boris to forsake his own party. The Tory candidate can't win in his Islington South patch, so he might as well pick between the Labour and Lib Dem candidates, who can. Indeed, on his vote could hang the outcome of not only that seat but the entire general election. Can he resist exercising such awesome power?
