There is this phenomenon in the United States called Monday Morning Quarterback.
It describes a person who says that he or she always knew what the outcome of the Sunday football games was going to be and proceeds to give an explanation for why the game resulted in the eventual result. In other words, this person is passing judgment from a position of hindsight, which is always 20/20.
I could easily play this game in regard to the upcoming Terengganu by-election. It would be far too easy for me to list down, on Sunday, reasons as to why PAS won the by-election and at the same time, to have ready an alternative list of reasons as to why the BN/Umno managed to win the same by-election in case of an upset.
