Everyone knows voting in a general election is kept a secret. The only people who will know who voted for whom is the Election Commission although they may deny this but by verifying the serial number in the ballot papers, the EC official will be able to say for sure who voted for whom.
The Prime Minister had remarked that the Chinese betrayed the Barisan Nasional by not voting for their candidates.
Unless the EC officials had disclosed this confidential information to the Prime Minister, could the Prime Minister confidently say that the Chinese had not voted for the Barisan Nasional. There are also Malays, Indians and others in the urban areas, but why were they not blamed.
It seems the Election Commission had failed to uphold the basic principle of secrecy.
