Ian Tsung-yen Chen, an assistant professor at National Sun Yat-sen University, said there was little in common between the political bases of Gou and Han.
"Gou's supporters are not deep blue [KMT] voters and they were not Han fans from the beginning... I don't think votes for Gou will significantly swing to Han," Chen told Nikkei. "Unless Tsai Ing-wen makes major mistakes, she has the upper-hand in this election."
