How many GRCs would possibly be up for election? Excluding
SMCs.
1) Bukit panjang (Aiyah, don't say better lah.)
2) Tampines (My best bet)
3) Aljunied (Why bother?)
4) Toa Payoh (Hard but worth a try)
5) Ang Mo Kio (Another why bother?)
Bukit Panjang is not a GRC. It's a SMC.
Other GRCs which might see contests are
Jalan Besar
Pasir Ris - Punggol
