The opposition in Sarawak will normally shun Dayak constituencies during a general election - the reasons are obvious.
In most cases, the chance to defeat the Barisan Nasional is almost zero. Contesting a rural seat in Sarawak is a very expensive affair and there is no way for the opposition to match the huge resources and machineries of the BN.
At best, it will only be a token fight should the opposition decide to enter the race.
