The Peoples’ Democratic Party (Halkların Demokratik Partisi [HDP]) was one of the leading actors in Turkey's double parliamentary elections in 2015. Under the leadership of Selahattin Demirtaş, it has enjoyed great success, crossing the ten percent threshold and entering parliament in the June 7, 2015 elections. Yet the hype was mitigated by the party's poorer results in the November 1, 2015 elections. This electoral performance manifested the strengths as well as the limits of the HDP's ability to maintain its support in a polarized political environment. Yet the HDP remains an indispensable actor for the peaceful resolution of the Kurdish issue. © 2016 Taylor & Francis.
