From the Bangkok Post online:

The People’s Alliance for Democracy (PAD) is betting its future on Tuesday’s showdown with the government with confidence that Prime Minister Samak Sundaravej and his cabinet will be toppled.

Calling today’s showdown “the last whistleblow”, Sondhi Limthongkul, one of the PAD leaders said: “If we fail this time, we’ll quit and surrender the country to them. When people don’t care about us, we won’t have to care about them. Let others take over the country.”
