The APC gained a net total of 21 seats compared to the pre-election situation.

[5] Before the 2019 general election, dozens of lawmakers had defected from their original parties leading to a vastly different House compared to swearing-in day in 2015 as the APC barely held onto its legislative majority due to waves of defections.

In the results, dozens more lawmakers lost in party primaries or in the general election with notable general election seat flips included several in Kwara State where the Ó Tó Gẹ́ Movement against the Saraki dynasty and the state PDP swept out five all PDP-held seats.

In more perceived rebukes of political godfatherism and party switching, the House members that followed Akwa Ibom North-West Senator Godswill Akpabio into the APC all lost while most Kano House members that defected to the PDP along with outgoing Kano Central Senator Rabiu Kwankwaso also lost their seats.

Other major stories were rapper Banky W. (MDP) losing in Eti-Osa but winning two polling units and pulling nearly 14%, Speaker Yakubu Dogara (PDP[e]-Bogoro/Dass/Tafawa Balewa) winning re-election in his constituency as Senate President and fellow APC-to-PDP defector Bukola Saraki lost his senatorial district, the closeness of longtime House member and Minority Leader Ogor Okuweh's re-election in his Isoko South/Isoko North constituency, and the several seats won by APGA across the Southeast.
