u really believe the bullshit teochew factor the govt approved media was sprouting over the years? I lived in punggol and was forced relocated to hougang in early 80s. most hougang electorate were from punggol. if u check GE result over the years, punggol voters voted resoundingly to pap since 1965. so why in 1991, the voters turned against pap?
the real reason was after forced relocation, many lost their only mean of income and fell into hardship. being illiterate or not kangtang speakers, many find it difficult to find work. Only jobs available were low paying manual work, while being farmers or fishermen also hardwork but the income were better and also can live off the land and sea. Moving to hdb mean everything also must pay. To make matter worse, they see their old lands abandoned(land bank) without development so many were bitter why they kenna forced out with only pittance compensation. so in 1991, 53% voted for WP LTK as a protest vote. I still remember watching the rally at the ave 5 park jogging track while LTK spoke on top of a lorry that was parked in blk 326 carpark. He was an unknown then so why 53% voted for him, a swing vote of 12% from 1988 result? life was really hard during 1980s recession and the ex-punggolites suffer the brunt of it.
by the way, I not teochew. my old man and mom voted for LTK in 91 and never look back.
it the same thing as the old chengsan estate which is practically also hougang. but the main dialect group in chengsan is hokkien, not teochew, so cannot use the teochew factor as a reason to explain why WP is popular over there.
