Ya, but who will bell the cat?
That the problem. Every party leader is answerable to their party and members to do well and will be deem as betrayal to the party interests if they compromise too much. Hence no one wants to get their hands dirty for the sake of opposition unity.
In the end oppositions end up like splinter groups of guerilla pitting against a regular Army that is highly integrated with all the fire-support. How to win?
I suggest.
1. KJ should lead a team to fight with old fart. Old fart is passe even if he lose will be of no lose to the country. Sending in a suicide squad he won't even brink an eye and may continue to give fire support in other ward. to take on him opposition needs to send in someone with substance. In addition since he is the daddy of PM, he still can provide advices to his son on a personal capacity. best of all no need to pay him taxpayers dollar.(opposition should remind this fact to voters). I know it maybe a bit unfair but chances of a freak result are pretty good if there is good candidates from opposition. I can't think of anyone better than KJ.
2.As for GCT, he do not have the type of charisma old fart has but still capable of inflicting some damages. We need to keep him busy, would suggest that WP send in their "B" team to counter him.
3. For PM GRC, stakes are high, if anything goes wrong there will be no one to lead. Thus opposition only need to send in a suicide squad and pinky won't dare to take chance. Also if opposition send in their A" team, it may scare people even more to vote for PAP as the possibility of PM losing becomes very real. So why not opposition send a combine team consist leaders of their youth wing? It could also help to build rapport and understanding among future opposition leaders.
With these 3 keep busy in their own wards, it will free up our other teams to fight their own election campaign without much interference. Other uncontested ministers are pretty much sitting ducks as they can't pull the crowds.
