If a candidate is also a resident in his own GRC, does it mean ownself vote oneself?

[Balls2U]

Has such a scenario happened before?

 

[A Singaporean]

Yes. Can vote for yourself or even opposition.

 

[laksaboy]

That's the norm. In other civilized countries, the candidates' ownself vote is often also used as press photo op.

Of course!

Ownself vote ownself! Vote is secret.
