Fig. 8. (Color online) Google Trends during the period of resignation of major candidate(left panel) and unification of candidates(right panel). The left panel shows the case in which Ahn resigned midway in the 18th presidential election, and the right panel shows the case where Ahn unified with Yoon in the 20th presidential election.
