Analysts say it's an Olympic tussle, an election battle to win control of London's City Hall just weeks before thousands of athletes and spectators arrive in Britain's capital for the Summer Games. But local elections being held Thursday May 3, 2012 across Britain, including a vote for London's mayor, could have more far reaching repercussions _ catapulting Boris Johnson, the capital's famously outspoken, but well liked leader, on a path to national power.
