Editor's Note: This is the first installment in an ongoing series focusing on Nigerian elections, the politico-militancy dynamic of the country's Niger Delta and proposed reforms of the country's energy sector. Nigeria's presidential election began April 16; gubernatorial and local government elections will follow on April 26. Owing to the power of incumbency, Nigerian President Goodluck Jonathan is in a strong position to win re-election, and his membership in the dominant ethnicity in the Niger Delta region means he will be able to keep violence in check in the oil-rich area. The question now becomes how the 2015 election will turn out, an election whose calculus will be defined by the so-called "zoning agreement" hashed out in the late 1990s. (click here to enlarge image) Jonathan, for example, belongs to the Ijaw, the dominant ethnic group of the Niger Delta. This region had been neglected in Nigerian national power plays until he became president. The Ijaw in particular and the Niger Delta (also referred to in Nigeria as the South-South Zone) more generally have struggled to achieve power on a national level. Throughout Nigeria's post-independence history, the area sat on the sidelines while the country's three dominant regions and groups — the North, the South-West and the South-East, generally populated by the Hausa-Fulani, Yoruba, and Igbo ethnic groups respectively — jockeyed for material and political gain. Jonathan's rise disrupted the zoning agreement. Had Yaradua not died, under the agreement, he would have been supported for a second term as president that would have run from 2011-2015; Jonathan would have continued to serve as his vice president. Jonathan's assumption of the presidency deprived northerners of five of the eight years that they were entitled to under the agreement. Though the break in the zoning agreement could trigger politically motivated violence, northern political elites may yet emerge in an advantageous position. When he became president, Jonathan selected Namadi Sambo, a former governor of Kaduna state in the North-West Zone, to be his vice president. As such, Sambo will be the front-runner to succeed Jonathan in 2015 — assuming Jonathan keeps his promise to serve only one full term. Should Jonathan change his mind, perhaps caving in to pressure from his supporters, it would be politically difficult for him or another southerner to win the presidential nomination in 2015. Should Jonathan step down in 2015 as planned and the two terms foreseen by the zoning agreement stand, Sambo will govern as president from 2015-2019 and 2019-2023. The South-South will bow out of national office in 2015, and the front-runner for the vice presidential slot will probably be someone from the South-East Zone. Given the advantages of incumbency, Jonathan is well positioned to remain Nigerian president through 2015, something not expected when he was first elected to national office in 2007. Under the previous arrangement, his support base in the Niger Delta would have had to wait a generation to hold the presidency. Militancy in the Niger Delta is therefore not necessary to promote the political interests of the Niger Delta — and could actually undermine Jonathan's candidacy and credibility. Not surprisingly, Jonathan's colleagues at the state level from his home region — the governors of the primary oil-producing states, Delta, Bayelsa and Rivers — all support the PDP re-election effort. These incumbent governors do not need to resort to militancy to secure their political ambitions. Instead, they must support Jonathan's candidacy and keep militancy in check. The Niger Delta region has ceased to be a national pariah under Jonathan and his predecessor Yaradua, but Jonathan's relationships with the militants give him the unique power to manage tensions in his home region and safeguard oil production in the area. This is not to say that there are not disputes, rivalries and related political violence in Nigeria and especially the Niger Delta. But the drop in militant attacks against energy infrastructure stands testament to the government's ability to keep a lid on violence. Jonathan is in fact likely to keep militancy in the Niger Delta in check during his entire term. In addition to Jonathan's support from the South-South, his selection of Sambo as his vice president and possible successor undermines the Buhari-led CPC opposition in the country's North-West Zone. Whatever grassroots support Buhari and the CPC hope to gain in the North-West will be doubly difficult. Sambo not only enjoys the full patronage and perks of the incumbency provided to him by the PDP, he is also the heir apparent on behalf of the region that would lose out on the 2015-2019-2023 terms (to the South-East) should Buhari win the election. The question moving forward has thus moved to what political rivalries will emerge in 2015, and what means will be employed to secure the claim of a certain region to the presidency.
