The Buharimeter is an independent monitoring tool that enables Nigerians, scholars and political analysts around the globe to evaluate the implementation of the campaign promises of President Muhammad Buhari and his party, the All Progressives Congress (APC), made in the prelude to the 2015 general elections. Like other election pledge monitoring initiatives around the globe (such as Obameter, Mackymeter and Morsimeter), Buharimeter evolves out of the concern to address the challenges of governance, civic participation and effective service delivery in Nigeria. Its central focus is to bridge the existing gap between the government and the governed, thereby facilitating a process through which democratic accountability becomes the norm. By analysing data gathered through multiple sources and rating the performance of the government, we hope to empower Nigerians to take an active role in making the APC-led government live up to its campaign promises.
