Osun 2026: 10 LGAs that could decide the governorship election

As voters across Osun State head to the polls, the battle for the Government House in Osogbo may ultimately be decided not by the overall statewide vote alone, but by the margins recorded in a handful of strategically important local government areas.

The contest between incumbent Governor Ademola Adeleke of the Accord Party and the All Progressives Congress (APC) candidate, Munirudeen Bola Oyebamiji, is expected to be closely fought, putting renewed focus on areas with large voter populations, entrenched party structures, strong political identities and a history of competitive results.

Although all 30 local government areas will contribute to the final tally, their electoral weight is far from equal. In some, tens of thousands of votes are available; in others, the difference between the leading candidates in the last election was so narrow that a relatively modest swing could dramatically alter the statewide arithmetic.

1. Osogbo: The Biggest Electoral Prize

With 167,704 registered voters, Osogbo is the largest electoral constituency among Osun’s 30 LGAs, accounting for about 7.17 per cent of the state’s voter register.

But Osogbo’s significance goes beyond its numbers. As the state capital and centre of political activity, it has traditionally attracted intense competition between the major parties.

In the 2022 governorship election, Adeleke secured 30,401 votes in the LGA, defeating the APC’s Gboyega Oyetola, who polled 22,952 votes. Adeleke’s 7,449-vote advantage represented a substantial contribution to his eventual statewide victory.

The 2026 contest could therefore turn Osogbo into one of the earliest indicators of the direction of the race.

For Oyebamiji, a major improvement over the APC’s 2022 performance could provide thousands of additional votes. For Adeleke, retaining his previous advantage could provide an important buffer against potential losses elsewhere.

2. Olorunda: The Other Capital-Area Battleground

Olorunda, with 123,063 registered voters, reinforces the electoral importance of the Osogbo axis.

Combined with Osogbo, the two LGAs account for 290,767 registered voters, representing roughly 12.4 per cent of Osun’s entire register.

Adeleke won Olorunda in 2022 with 21,350 votes, while Oyetola recorded 18,709, leaving a margin of 2,641 votes.

Although smaller than Adeleke’s margin in Osogbo, the difference was politically significant. In a closely contested election, thousands of votes gained or lost in a single LGA can materially affect the statewide outcome.

Oyebamiji will therefore be looking to narrow or overturn Adeleke’s advantage, while the incumbent must defend the gains made in the capital area four years ago.

3. Ife East: A Large Electoral Reservoir

Ife East has 128,515 registered voters, making it Osun’s second-largest LGA by voter population.

Its importance becomes even clearer when considered alongside Ife Central and Ife South. The three LGAs collectively have 317,224 registered voters, equivalent to approximately 13.6 per cent of the state’s register.

Yet Ife East was an APC stronghold in the 2022 election, albeit by a relatively narrow margin. Oyetola polled 19,353 votes against Adeleke’s 18,071, giving the APC a lead of just 1,282 votes.

That margin makes Ife East particularly vulnerable to a swing.

A relatively small change in turnout, mobilisation or voter preference could transform the LGA from a narrow APC advantage into an Adeleke victory—or widen the gap in favour of Oyebamiji.

4. Ife Central: APC Advantage Under Pressure

With 122,454 registered voters, Ife Central is another heavyweight on the electoral map.

The APC also carried the LGA in 2022, with Oyetola securing 17,880 votes against Adeleke’s 13,532. The 4,348-vote margin gave the APC a significant advantage in one of the state’s largest voting blocs.

For Oyebamiji, maintaining or expanding that lead would provide an important reservoir of votes.

For Adeleke, however, improving his performance in Ife Central could be just as consequential as defending his established strongholds.

The presence of third-party candidates could further complicate the calculation. Even a modest redistribution of votes among the leading contenders and other candidates could change the margins separating Adeleke and Oyebamiji.

5. Iwo: The Classic Swing LGA

Iwo has 106,814 registered voters and stands out because of just how close the 2022 contest was.

Oyetola won the LGA with 17,421 votes, while Adeleke recorded 16,914—a difference of only 507 votes.

That razor-thin margin makes Iwo one of the clearest swing territories in the election.

A shift of a few hundred or a few thousand votes could completely reverse the previous outcome. Turnout, grassroots mobilisation and candidate appeal could therefore become decisive.

Whichever campaign succeeds in converting Iwo’s large electorate into a clear advantage could gain an important edge in the statewide race.

6. Ede North: Adeleke’s Stronghold Faces a New Test

Ede North has 96,644 registered voters, placing it outside the state’s very largest LGAs. Yet its political significance is much greater than its raw voter population suggests.

The LGA is one of Adeleke’s traditional political strongholds and played a major role in his 2022 victory.

He secured 23,931 votes against Oyetola’s 9,603, producing a commanding 14,328-vote margin.

That figure is particularly important in understanding the electoral mathematics of Osun. A candidate does not necessarily need to dominate the largest LGAs if he can build substantial margins in smaller but politically loyal territories.

The major question for 2026 is whether Adeleke can reproduce that level of dominance.

Oyebamiji’s immediate objective will likely be to cut deeply into the incumbent’s advantage. Adeleke, meanwhile, needs to preserve Ede North as one of his most productive vote sources.

7. Ede South: The Incumbent’s Other Major Fortress

Ede South may have only 67,729 registered voters, but its 2022 result demonstrates why voter population alone cannot determine electoral importance.

Adeleke won the LGA overwhelmingly, polling 19,438 votes against Oyetola’s 5,704—a staggering margin of 13,734 votes.

Combined, Ede North and Ede South have 164,373 registered voters, approximately seven per cent of Osun’s electorate.

For Oyebamiji, the objective may not necessarily be to win Ede South outright. Reducing Adeleke’s margin could itself be strategically valuable.

Conversely, if Adeleke maintains overwhelming support across both Ede LGAs, the combined margin could provide him with a substantial cushion to withstand setbacks elsewhere.

8. Irewole: Oyebamiji’s Home-Turf Test

Irewole has 96,528 registered voters and carries an additional political dimension because Oyebamiji hails from Ikire within the LGA.

The APC won the area in 2022, with Oyetola polling 18,198 votes against Adeleke’s 14,216, a margin of 3,982 votes.

The 2026 election will therefore serve as a direct test of Oyebamiji’s ability to convert personal political identity and local structures into votes.

A decisive APC victory could help compensate for potential losses in other parts of Osun West.

But if Adeleke substantially narrows the previous gap, or if third-party candidates attract a meaningful share of the vote, the result could become one of the more closely watched indicators of Oyebamiji’s political strength.

9. Ifelodun: A Potential Tipping Point

Ifelodun has 94,870 registered voters and belongs to the group of LGAs where the previous contest was decided by a relatively small margin.

Adeleke won the LGA in 2022 with 17,107 votes, compared with Oyetola’s 16,068—a difference of only 1,039 votes.

If the statewide contest is as close as expected, Ifelodun could prove particularly valuable because its electoral significance lies not only in its size but in its capacity to swing.

10. Ilesa East: The APC’s Test Across the Ijesa Axis

Ilesa East has 89,491 registered voters and represents another important battleground for the APC.

Oyetola won the LGA in 2022 with 13,452 votes, while Adeleke polled 10,969, giving the APC a margin of 2,483 votes.

The LGA’s importance, however, extends beyond its individual numbers.

Ilesa East, Ilesa West, Atakunmosa East, Atakunmosa West and Obokun collectively account for more than 332,000 registered voters, making the wider Ijesa axis one of the most significant electoral blocs in Osun.

A strong APC performance across the axis could provide Oyebamiji with a substantial base of votes.

Adeleke, on the other hand, will be looking to prevent the region from becoming a major source of opposition votes and potentially narrow the APC’s previous advantage.

The Bigger Electoral Calculation

The 10 LGAs highlight a central feature of the Osun governorship contest: the election could be determined as much by margins as by outright victories.

Adeleke’s 2022 victory demonstrated the value of accumulating large margins in loyal territories while limiting losses in opposition strongholds. Oyebamiji’s challenge is to reverse that equation—protect APC territory, make significant gains in swing LGAs and reduce the incumbent’s advantage in areas traditionally associated with Adeleke.

The geographical pattern also creates competing electoral strategies.

Adeleke’s strongest defensive positions include the Ede axis and parts of the capital area, while Oyebamiji can look to the Ijesa and Ife axes, Irewole and other areas where the APC performed strongly in 2022.

The swing territories—particularly Iwo, Ifelodun and the closely contested Ife LGAs—could ultimately determine whether either candidate succeeds in converting regional strength into a statewide majority.
