Nancy Pelosi gives her support to the Dalai Lama in Dharamsala. A Presidential candidate couldn't do that -- China would come calling. Anyway this trip was arranged long before the "controversy" in Tibet (but anytime is a bad time to see the DL in China's eyes.)
“If freedom-loving people throughout the world do not speak out against China’s oppression in China and Tibet, we have lost all moral authority to speak on behalf of human rights anywhere in the world,” Ms. Pelosi, Democrat of California, told an overwhelmingly Tibetan audience of around 2,000 people in the courtyard of the town’s main temple, Tsulakhang.
The visit by Ms. Pelosi, accompanied by nine other members of Congress, most of them Democrats, was arranged some time ago as part of a visit to India.
