Both men have devoted their energies to transport -- and attacking each other viciously on the issue, as well as on their complex personal tax arrangements.About 6 million Londoners are voting to elect new mayorRole largely ceremonial but mayor controls $23 billion budgetFront-runners are incumbent Conservative Boris Johnson and Labour's Ken LivingstoneTransport is key issue, especially design of city's famous red buses

Riverside, California (CNN) As she has trudged toward the Democratic nomination, Hillary Clinton has struggled to find a message that could impassion her Democratic voters the way her rival Bernie Sanders has. But that changed this week in California when she turned her full attention to Donald Trump. With the brash real estate magnate as her full-time foil, Clinton finally seemed to find her voice. In speech after speech across the Golden State, Clinton delivered a fiery, point-by-point takedown of the real estate magnate, casting him as a greedy bully who was eager to profit from the financial woes of the middle class Americans who lost homes and jobs in the 2008 economic crash.Clinton has amped up her attacks against Trump while campaigning in California this week"The fact is Donald Trump thought he could make money off of people's misery," she said
