The tallest man will win?

In US politics it has become axiomatic that the tallest man wins the Presidential Election, so I was wondering how this fitted in with the Labour leadership campaign but Max Atkinson is ahead of me:

'height puts Balls and Burnham in 3rd and 4th place respectively, leaving the Miliband brothers in equal first place at 5 ft. 11 ins.'

Don't write off Ed Balls he may not have the height but he has got the union backing.
