Until approximately two decades ago, the Democratic Action Party (DAP) struggled to make inroads in Johor due to: (1) the unique historical developments in the state, which benefited its primary opponent Barisan Nasional (BN), and (2) the decentralized party structure in Johor with party branches serving as the main player responsible for grassroots mobilization and campaigning, which resulted in an underdeveloped and less cohesive state party structure. Despite Lee Kaw playing a crucial leadership role for the nascent party to take root in the state, Johor remained in the periphery during the initial decades of the party's establishment. The party managed to achieve some electoral success only in central Johor around the Kluang. The party achieved a rare breakthrough in Johor during the 1990 General Election when numerous Chinese educationalists allied with the DAP under the call of then Dong Zong chairman Lim Fong Seng. However, the national alliance frayed soon after, with the DAP losing its momentum in Johor by the next general election. In the aftermath of GE2008, where DAP made unprecedented gains in Penang, Selangor and Perak, the national DAP leadership shifted their attention towards Johor as the latter was perceived as the next frontline state. The party continued its upward swing and made unprecedented gains in the 2013 General Election. As DAP maintained its momentum, coupled with the success of other Pakatan Harapan (PH) component parties in Johor during the 2018 General Election, the DAP under the PH coalition displaced BN as the Johor state government.
