All around Liu Huizhen’s makeshift house, clusters of men lurked and smoked on a recent day, suspiciously eyeing passersby. Dozens of uniformed police waited in reserve, ready in case of trouble, while a thuggish man stood in the middle of the road with arms defiantly folded, preventing cars from passing. Liu, a 45-year-old farmer’s wife, appears to have the Communist Party worried, here in the village of Gaodiansan on the outskirts of Beijing. She wants to exercise her constitutional right to stand in local elections due to be held in the capital on Nov. 15, and about a dozen supporters had arrived to help her begin her campaign. They were to be blocked by a decisive show of force. “Some people think I am a troublemaker,” she said. “They think this is the government’s decision and I won’t win in the end. But I am not afraid. I have the right to participate in this election. I didn’t do anything illegal.”
