This work evaluates the political process and governance in Nigeria between1999-2018 with emphasis on
the role of the National Assembly and Independent National Electoral Commission (INEC). The political
process comprises the totality of the ways and means of acquiring and exercising governmental authority in
a political system. It is the systematic series of actions and guidelines involving relevant institutions that
impact on the quest for the exercise of political power in governmental or public affairs of a country or state
through periodic elections. The broad objective of the thesis centered on the evaluation of how the role of the
National Assembly and Independent National Electoral Commission could enhance good governance in
Nigeria. It employed the survey method of research design in which the data required for the study were
generated through the instruments of questionnaire, and in-depth interviews. Quota and stratified sampling
techniques were mostly used in the selection of respondents. Four hundred and thirty copies of
questionnaire were administered and 360 were returned. The data were analyzed using linear regression
analysis, as well as inferential statistics, tables, frequencies, percentages and graphs to crystallize and
present the results. The findings among other things indicate that both the National Assembly and
Independent National Electoral Commission have not satisfactorily performed their constitutionally assigned
roles of enhancing the political process and good governance in Nigeria between 1999-2018; that the
National Assembly has not been able to represent the collective interest of the masses; that the inability of
the National Assembly to enforce the provisions of the 1999 constitution as they relate to cross-carpeting of
politicians elected into the National Assembly or any other elective office in Nigeria is because such an
amendment and interpretation will adversely affect the National Assembly members who are currently
benefiting from the dispensation; and that although the introduction of technology in the management of
elections will help advance the political process in Nigeria, however, due to poor voter education, the huge
amount spent for this project would be a colossal national loss except urgent steps are taken by INEC to
embark on appropriate voter education to enable the electorates and masses know how the technological
equipment are used to facilitate free and fair elections subsequently in Nigeria with a view to advancing
democracy in the country
