The one planted will not have the means to usurp you in power. At best, victory in a SMC or GRC. His handlers continue to call the shots. He/she is merely a pawn.
There was a risk taken with LTK's entry to Aljunied. What if he had stayed at HG? Would the WP have won in Aljunied? Even though in power for the past 5-6 decades, there are things the PAP cannot control.
Don't think his handlers call the shots either as there are things that even the PAP cannot control and that is the mood of the people and how they vote. Even within the parties, the PAP, the WP or the SDP, many things cannot be controlled by the top leaders. BE PE 2013 was a very good example within the SDP.
I am sure, it is very disturbing for the PAP to suffer three consecutive defeats to the WP: Aljunied, BE HG and BE PE. Except for HG, the other two are both landmarks, not only for losing but for the manner that these were lost.
It is for these reasons that the PAP now have to swallow wounded pride to review core principles in their policy making. Although appearing very limited and slow to most people, they are trying to tackle the FT issue without causing an economic backlash.
There are also initiatives to try and arrest the cost of living issue with the new housing policies, at the same time solving a few other issues along the way, like the issue of singles and divorcees and surprise of surprises the TFR issue by facilitating the married couples to be housed earlier.
I also see a much belated attempt to grow the local enterprises with the SME schemes but this could already be too late.
The transportation issue is a harder nut to crack and probably would have to wait for 2030 to have it finally settled. The first step to me, is the shifting of the control from car ownership (COE) to road usage and that will come around the time of the next GE with the introduction of the GPS system. With that PAP will not have to answer why the only the rich can buy a car but not the poor.
More need to be done to bring down the cost of living further (and all these somehow are related to property cost) so that consumerism and domestic economy can develop into another engine of growth instead of just relying on export sectors which are extremely volatile.
Whether all these changes can bring about a turn of luck for the PAP it is very difficult to tell. The fence sitters might possibly swing back but the longer trend of voters wanting a strong effective second, maybe a third voice, will continue to grow.
If the PAP continues to lose popular votes and seats, I can't see why internal problems like what we see in SDP will not crop up in the future. These are people solidly behind the Party. What is it for people who are just agents?
