Su Tseng-chang
In 2012, Su Tseng-chang, chairman of the Democratic Progressive Party, expressed support for same-sex marriage. Despite some division within the party on the issue, DPP's victorious presidential candidate for the January 2016 election, Tsai Ing-wen, announced her support of same-sex marriage in November 2015. She is the first major party candidate to come out in support of same-sex marriage.
