Marco Werman speaks with political cartoonist Joel Pett of the Lexington Herald Leader about the cartoonists he met on a recent trip to China. Pett says there are two types of political cartoonists in China: Older men employed by established state-run media outlets who adhere to the party line and younger Web-savvy cartoonists whose work appears in the commercial media and on blogs, Facebook and Twitter. One of the most talented and gutsy is Kuang Biao. He's dared to comment on subjects as sensitive as China's tainted milk scandal and the now-in-exile activist Chen Guangcheng.
