The thinking goes like this. What are the opposition parties trying to do? It is clear as day light that going on more than a straight fight would put their chances of winning very low. 3 corners are as good as losing outright. Anything more might as well forget the trouble, save the money and effort and don’t waste the people’s time. All they could gain, perhaps, is some cheap air time, some cheap publicity, to say a few angry words to the people. What else do they seriously think of achieving in a 5 corner fight? To prove their stupidity?
The other thinking is that there are moles present in the opposition parties that want to deliver the seat to the PAP. But the people would not know who is the mole, or how many are moles. And knowing that the outcome is going to be a PAP victory, might as well deliver the votes to the PAP and teach the clowns or moles a lesson. This could be an explanation of the final result. And there is no need to curse and swear for the missed opportunity just like the President Election. There is no point in blaming the other candidates that they should have pulled out of the race.
When opposition parties are thinking of having a wild party in every by election, to have a good time at all cost, they are not going to get any sympathy vote from the people. The people may be daft, but not silly. If the opposition parties are not serious and wanting to make every by election counts, why should the people take them seriously?
Under the present circumstances, with 5 parties contesting, my crystal ball is crystal clear who the eventual winner will be. No need guessing.
