Ed Miliband, who hopes to become prime minister on May 7, urged voters to choose hope over fear at a rally for activists Saturday. Miliband is fighting Prime Minister David Cameron for the keys to Downing Street in a knife-edge race which commentators predict could result in another coalition or a minority government for Britain.
