I do remember in 1984 when he made several threats and promises during the GE. I was a kid then but he recounted how the Tunku or Mahathir stopped all government building projects in constituencies which voted for the opposition. And he quite smugly said that the constituencies later elected UMNO in.
And to put his money where his mouth was I believe both Hougang and Potor Pasir paid that price.
Now that Aljunied is an opposition GRC will four constituencies pay that price?
