There were many challenges involved in the conduct of the elections. For example, the people had to cast votes among 16 presidential candidates (2 candidates withdrew two days before the elections) in some 25,000 polling stations across a country with geographical difficulty, uncertain security and inexperience with voting. In addition to about 10 million voters that are reportedly subject to multiple registering in some regions and under-registration in others, some 1.5 million refugees in Pakistan and 800,000 in Iran were expected to vote. Many concerns in the economy like re-exports, cultivation of poppy are discussed.
