The current president of Nigeria has, in the past - when he was a presidential candidate, but had not actually won in any election after repeated attempts - made multiple statements essentially condoning violent activity if, in his view, Nigeria's presidential elections were not free and fair. He was investigated in 2011 by a government panel for the role that certain comments that he made before the 2011 election may have played in the post-election violence that was carried out by his supporters after his loss. In 2012, he made remarks about the country's next elections, in 2015, and how they would possibly be "bloody" if he did not consider them to be free and fair. Since he won that one, there were no massacres carried out by his supporters. If he had lost, it might have been a bloodbath even worse than the 2011 violence.Nigeria is a failed state. It does not really have a "government."
As for his presidency, he has, of course, achieved very little (despite padded "lists of achievements" that his presidency has published repeatedly) and has even had to spend months away from his job because he was not even medically fit for the position he had campaigned for years to win. After all the fiery speeches and threats - threats which probably were the cause of the violence in 2011 that left hundreds dead - when he actually wins the presidency, he does very little of substance while in office, and it turns out that he is not even physically fit for the position.
This is the sort of person that was elected president of one of the most populous countries in the world.
