PAS responsible for voters running away to BN

Pakatan, through its partner, PAS,  lost again, this time in the Merlimau & Kerdau by-election. The loss is however expected, as Merlimau and Kerdau are BN's stronghold. What is not expected is that the loss is accompanied by a bigger majority for the BN. These are the fourth and fifth straight by-election losses suffered by the Pakatan coalition with increased majoirty. But what is most frustrating was the things that PAS and DAP did to give the extra votes to the BN. thereby increasing its majority. Haven't they learnt from the 2008 tsunami whereby the Indians were angered and subsequently gave Pakatan the necessary Indian votes? In the currect situation, why must PAS come out to push the gambling issue just before the by-election? Then why must Anthony Loke of DAP rebuke PAS for its action? Then we have Karpal Singh of DAP and Mustafa Ali of PAS making statements in support of their different stand. How can they ever think of Putrajaya when they can't even stay united over small matters, or at least hold back and discuss such matters in private? The increase in the BN majority showed that the squabbling among the Pakatan coalition is driving voters away, and it is a signal for its leaders to ring the alarm bell.
