Judging from recent events, the ruling coalition in the Malaysian state of Sarawak is feeling very unsure of its ability to retain its two-third majority in tomorrow's state election.

Not only are the rallies of the Barisan Nasional (BN) not drawing the crowds, its candidates are failing to excite voters except through offers of money and apparent quid pro quo development.

This has caused Prime Minister Najib Razak and a host of other Federal Cabinet ministers to fly to Sarawak to provide whatever support they can to their coalition partners there.

Long-time Chief Minister Taib Mahmud has adamantly refused to provide his apprehensive allies with a definite date for his retirement from office. While the Prime Minister has publicly stated that the Chief Minister would leave after the elections, Mr Taib himself, claiming that he has been grooming a successor, said he will not leave until sometime in the middle of the next mandate period.

The Prime Minister's concern is national, while the Chief Minister is about securing his own retreat. Mr Taib's defeat may not be on the cards but an impressive advance by the Pakatan Rakyat (PR) in Sarawak three years after its triumphs in the last general election will ensure it smoother sailing into the next one.

Breaking BN's two-third majority in Sarawak would be a bonus for the PR.

The BN's Achilles heel this weekend may not be Mr Taib's party, the Parti Pesaka Bumiputera Bersatu (PBB), but the Chinese-supported Sarawak United People's Party (SUPP).

The latter is the one feeling the heat of the effective campaigning being carried out by the opposition Democratic Action Party and Parti Keadilan Rakyat.

In desperation, it has now called in the top brass of the Malayan Chinese Association (MCA), the Chinese-supported BN member from West Malaysia. MCA president Dr Chua Soi Lek, secretary-general Kong Cho Ha and former party president Ong Tee Keat have all agreed to fly in.

Being politicians who have recently suffered bad drops in voter sympathy and moral standing, their presence may be more a bane than a boon for the SUPP.

It is doubtful that they can counteract the dynamic campaigning being carried out by the Opposition and its supporters. This is despite several key PR supporters being refused entry into the state.
