WOTC - By-election in Marsiling Yew Tee constituency

I asked this question in the Wisdom of the Crowd:

Should the govt call a by-election in Marsiling-Yew Tee Constituency?

Here are the responses: (40 Votes)

90 % - They should call a by-election to fill the vacancy created when Halimah Yacob vacated the job of MP.
5 % - What is there for the PAP to fear?
3 % - There is no need to call a by-election as her work is filled by the remaining MPs.
3 % - Wait for the decision of the Supreme Court on this constitutional issue.
