bro,
me was thinking the possibility of re-drawing boundaries for the constituencies is 吃饭戏 for the incumbent during GEs, but for a by-election at Hougang at this instance, me don't recall any restrictions set on the changes in the electoral boundaries.
but as we look at it now, the entire Hougang SMC is surrounded by Aljunied GRC, there will be an uproar if any part of the Aljunied GRC is touched or modified for this upcoming by-election
