WOTC - Contesting the general election

I asked this question in the Wisdom of the Crowd - What is the best way for the opposition parties to challenge the PAP at the next general election?

Here are the responses:

56% - By contesting in an alliance under a common symbol.
37% - By sharing a common platform on social and economic issues.
5% - By contesting as separate parties to offer a wider choice.
2% - By merging into one party
