Check up on the International Committee for Fair Elections in Taiwan at
http://www.taiwanelections.org/.
Their preliminary review, titled "Taiwan Elections 2012: Mostly free but partly unfair" can be read at http://www.taiwanelections.org/2012/01/15/taiwan-elections-2012-mostly-free-but-partly-unfair/.
Lastly, here's a nice article that interviewed some young Taiwanese-American voters that went back last week. http://www.lowellsun.com/todaysheadlines/ci_19765387#.TxbJsicaQFo.facebook
