CHONGQING, China — One of China's most flamboyant politicians is raising his political profile with a campaign to encourage the singing of Mao-era communist songs.

The "Sing Red Songs" campaign is one of several eye-catching policies that are winning praise for the 61-year-old Communist Party boss of Chongqing city and could propel him into the top echelons of the party leadership next year.

Bo Xilai has also won acclaim for cracking down on organized crime and empowering the working class. His rise may harken an era of more personality-oriented politics with a greater emphasis on policies favoring ordinary Chinese.
