The interpretation of the spoilt vote figures reveals the votes' feeling. In the papers today:-
"Spoilt votes was lowest in five constituencies where opposition parties fared the best. Hougang 1.13% whereas the national share of spoilt votes was 2.17%.
There were fewer spoilt votes in closely contested wards, or where the opposition was more viable, because the voter perceived that his or her vote was more likely to make a difference.
The percentage of spoilt votes was highest where PMLee(3.01%) and DPMTeo(2.85%) led teams against relatively weak opposition.
Where WP was the party challenging the PAP they were willing to vote for the opposition. But if there were no compelling opposition candidate , they would rather spoil their votes in protest"
