In theory, the process of political change, begun in 1982 by Rawlings and the PNDC, was a "bottom up" strategy to ensure the involvement of citizens in nation building. This stance resulted in the promulgation of the 1992 Constitution, the formation of political parties, the holding of elections in 1992 and 1996, and the building of a rural (including grassroots) political base in Ghana. One of the most distinctive characteristics in Ghanaian politics was that the Rawlings regime's commitment to liberal economic reform after 1983 did change its commitment to PNDC's original mandate. Before the implementation of Ghana's ERP, the Rawlings regime pursued radical economic redistribution policies by courting the support of low-income classes.
