It would appear that the Malay affirmative action programs are losing support among ethnic Chinese, see a long, thorough Reuters article on a Yahoo News website. The article leads this way:
Ethnic Chinese voters, upset over policies that favor majority Malays, have become increasingly alienated from Malaysia's ruling coalition, raising the risk of racial polarization.Multi-ethnic democratic countries are difficult to govern under the best of circumstances, as we know in the U.S. and our Canadian neighbors to the north know much better.
Footnote: The English-speaking majority in Canada has been effectively blackmailed for decades by their French-speaking minority. Openly blackmailed, and without shame, with the threat of separation. This scenario is unlikely in Malaysia.
