Because in countries like these, they can be voted out! The PAP has made so many blunders over years that I have no idea why they are still in power if not, why its not reduced to a minority government. It really boggles the mind that the people still voted for them.
Very sad about how the 60% have ignored the problems in Spore. They have waited too long. The damage to Spore is I think irreversible.
