WOTC - Strategies for non PAP parties

I asked this question in the Wisdom of the Crowd:

What should be the strategy for the non PAP parties?

Here are the responses: (47 Votes)

49 % - Form a coalition and have a common manifesto to offer voters the choice of electing a non PAP government
40 % - Have a common goal to deny the PAP a two thirds majority in the next general election.
11 % - Allow each non PAP party to contest its constituencies on its own manifesto but avoid three corner fights.
0 % - Continue their current practice and let the voters make the final decision.
