WSJ這篇點出了這次修憲複決的必要所在:

"A proposal to amend Taiwan’s constitution to lower the voting age from 20 to 18 failed to garner some nine million votes needed to pass despite clearing the legislature in a unanimous vote earlier this year.

For now, Taiwan remains one of few democracies in the world where a person turning 18 is required to pay taxes and becomes eligible for mandatory military services but is ineligible to vote."
