My opinion is that the sons of Jeyaretnam should reflect on the reality in these lessons:
(1) how and why their father was sued by the PAP political leaders, notably Lee Kuan Yew
(2) why in his hour of need, LTK turned against him
(3) despite his perseverance and emergence out of 17 years of wilderness, he died as a newly-discharged bankrupt whilst LKY and LTK were successful in terms of financial wealth
And what if the pants were sued off Kenneth, will the leaders in the Reform Party turn against him?
The battle is not just against the PAP. It is also watching your own back in your own party.
Thus, after these considerations, Kenneth is keen to run, then he will be running intelligently, benefiting from the mistakes his father had made.
Not to repeat them.
Phillip, on the other hand, can remain as an outwardly neutral party.
There is no need to put all your eggs in one basket.
