On the day of the election, each member of the electorate (most adult citizens aged 20 and upwards) stamped one from the two choices of president/vice-president tickets on the ballot. Since Taiwan does not provide absentee ballots, large numbers of Taiwanese expatriates living in North America and Mainland China returned to Taiwan to vote. Typical estimates indicate that about 20,000 people travelled from North America and between 100,000 and 150,000 people travelled from Mainland China. Most analysts believe that the voters from North America would be split evenly between the two candidates, but that those from Mainland China voted overwhelmingly for Pan-Blue.
