There is a basic premise in western politics that you do not have a referendum unless you already know the outcome.
Most politicians who have supported a referendum that did not fall the way they expected are no longer politicians.
The Australian “republic” referendum is a landmark case. Not only did Prime Minister Howard ensure that he knew the answer – but he also ensured it was the answer HE wanted.
Maybe it is refreshing that Taiwan might have a referendum where the answer is not already known.
