Your gas costs more because of this

From Reuters:

An amendment to Nigeria's constitution that could extend President Olusegun Obasanjo's hold on power was presented to lawmakers on Tuesday amid signs it lacks the support needed to pass into law.

The proposal has fuelled violence in Africa's top oil exporter ahead of elections next year and raised fears among civil society groups that it could be sliding back towards dictatorship.

How much does a barrel of oil cost? Again, from Reuters:

U.S. oil powered towards its $70 a barrel record on Tuesday, fuelled by a mix of investment fund money, strong demand in the United States and China and threats to supply from OPEC producers Nigeria, Iran and Iraq.

Hmm.
