Yes, but if you look at mature democracies which have first past the post systems like us - UK, USA, Australia, they all have 2 major parties. Maybe a much smaller third party. At this point it is already fairly apparent, if the WP does not collapse, that the 2 big parties in Singapore in the long run will be PAP and WP. Everybody else is basically competing for 3rd place. All the other opposition parties know at this point that there is a danger that they will fade in the long run.
