Are there swing voters in Taiwan?

Over at Taiwan Matters, I'm floating an argument that there are no swing voters in Taiwan:

Taiwan voters, I suspect, "swing" because they are following a crude version of the decision strategy known as "Take the Best." For example, in selecting a mate, if one values brains more than beauty, then if one has to choose between two potential mates, the smarter one will get the nod. If two candidates are equal in both brains and beauty, then choose randomly, because it doesn't matter.
