I think both the first 2 posts of this thread missed the point (of Sneering Tree, that is).
Scenario 1 tells you there are 9 parties in a hypothetical Singapore Parliament where none hold the majority. The largest party, WP, has 38 out of 113 seats and need 19 more. PAP has 12 seats and UFP (some new party formed 20 years from now) has 10. The 3 parties form a coalition of 60 seats to govern, despite past history between PAP and WP. The other 6 parties occupy the remaining 53 seats, each with about 2 to 15 seats - they form the opposition.
Scenario 2 has 2 parties, PAP with 74 seats, WP with 17 seats, both taking up all except 2 of the 93 seats which is under a new TJS party. It could have been 74 vs 19 but despite the lopsidedness, PAP and WP form a coalition and it becomes 91 vs 2.
There is a gulf of difference between 1 and 2. 1 looks very far away, 2 is possibly closer in the timeline. And more importantly, 1 is necessary, 2 is scary and negates necessity. Both are examples of PAP and WP forming a coalition, but lead to very different conditions. Pritam and Sneering points to 1, there are dishonest attempts to put it as 2.
