Factors that hinder the successful Operation of Democracy in Nigeria?

• Lack of an independent electoral commission that will conduct free and fair election.
• The propensity to win elections by all means on the part of politicians.
• High degrees of illiteracy and ignorance on
  the part of the electorates.
•  Obstruction of the duties of the electoral commission by some selfish politicians.
• Rigging of elections, which deprives the electorates the right to choose the right candidates.
• Absence of independent and impartial
  judiciary that can adjudicate election petitions.
• Rampant military coups that usher in
  undemocratic military administrations.
• Absence
  of free and fair press that can enlighten the electorates and also, expose election
  atrocities.
•  Interference in
  government by political parties.
