2023 Nigerian Senate elections in Bauchi State

The primary resulted in Uba Ahmed Nana emerging as the nominee after results showed him defeating former Senator Isah Hamma Misau by a 49% margin.[14]

On the primary date, former Senator Abdul Ahmed Ningi was the only candidate and thus was nominated unopposed.

In December 2022, analysis from The Nation categorized Ningi as the frontrunner due to his political clout and the relatively low name recognition of Nana.[21]

The primary resulted in Siraj Ibrahim Tanko Muhammad—son of then-Supreme Court Chief Justice Ibrahim Tanko Muhammad—defeating Ibrahim Baba for the nomination after results showed a 3% margin of victory; Bulkachuwa came last without any votes.[14] The win was controversial due to allegations that Muhammad used his father's position to steal public funds used to bribe delegates with cars, cash, and jobs in the judiciary.[23] These allegations purportedly led to Ibrahim Tanko Muhammad's resignation as Chief Justice in July 2022 amid other scandals as well.[24][25] The nomination itself was categorized as another example of the formation of political family dynasties as Muhammad was one of many political family scions to win primaries.[26]

The Azare-held primary resulted in victory for Sama’ila Dahuwa—former Commissioner of Health in the Bala Mohammed administration. Dahuwa beat chemist Laraba Gambo Abdullahi by a 27% margin of victory. In his acceptance speech, Dahuwa praised his former opponents and asked for their support going forward.[29]

The primary in Bauchi resulted in Shehu Buba Umar defeating Gumau for the nomination by just 6 votes.[30][14] Gumau promptly left the APC to run as the NNPP nominee.[31] The nomination of Umar was briefly annulled after a November court ruling, but the appeal ended with Umar's reinstatement as nominee.[32]

The national NNPP announced its primary schedule on 12 April 2022, setting its expression of interest form price at ₦0.5 million and the nomination form price at ₦2.5 million with forms being sold from 10 April to 5 May.[33] The rest of the timetable was revised on 19 May; after the purchase and submission of forms, senatorial candidates were screened by a party committee on 25 May while the screening appeal process was held on the next day. Ward congresses were set for 22 April to elect delegates for the primary. Candidates approved by the screening process advanced to a primary set for 28 May, in concurrence with all other NNPP gubernatorial primaries; challenges to the result could be made the next day.[34]

Originally Yakubu Shehu Abdullahi—MHR for Bauchi—claimed to have been given an "automatic ticket" by party leadership as NNPP nominee, a few days after he defected from the APC in May 2022. However, the party promptly held a primary after Gumau joined and nominated him unanimously instead at a primary in Bauchi on 5 June.[31] In response, Abdullahi labeled the primary as "a charade" and claimed to be "the authentic candidate of the NNPP."[35]

The primary resulted in victory for Dahiru Garba—former Commissioner of Commerce in the Bala Mohammed administration. Dahuwa beat Mahiru Maiwada by a single vote.[29] After tabulation, Garba asked for the support of his former opponents.[38] However, the ruling of a Federal High Court sitting in Owerri in mid-November 2022 annulled the primary and ordered the party to conduct a new exercise.[39] In compliance with the ruling, a rerun primary was held on 30 November with Garba winning by a wide margin; however, most other aspirants were absent from the venue.[40]

In review of the campaign in December 2022, reporting from The Nation categorized Gumau as the frontrunner due to the relatively low name recognition of his opponents and the controversial PDP primary.[21]
