They have already bought the electronic voting machines. It's vote rigging time. Even if they lose a few seats, it's pointless since the Lee family and cronies control all organs of society. If the opp take over parLEEment, LKY will call in the army.
But here's a wild card: I believe after LKY dies, all his cronies will simply fight with each other for power, or just fuck off. Their source of power and money is gone, why stay and do anything else here? The PAP might split. AssLoon gets no respect from anyone, even in his own party. Therein lies some hope.
