WP, under Marshall and JBJ had the support of the minority Malays and Indians.
After he backstabbed JBJ and took over the party, LTK turned what used to be a multi-racial party into a Chinese chauvinist party seeking to advance his narrow, Nantah-typed Chinese worldview. Away from the public facade he puts on and in private, he detests the minorities Malays and Indians, seeing them as a nuisance and impediments to the advancement of Chinese language, Chinese education, Chinese culture. This man is obsessed with all things Chinese. He suffers from some type of serious ethnocentric psychological disorder.
The Malays and Indians took a risk and gave their conditional support to the WP which enabled it to win Aljunied. The dumb WP chauvinists, racists and "Guess the Race" bigots have squandered that temporary support and goodwill.
