Some 6.4 million voters in Zimbabwe -- about half of the country's population -- will be eligible to cast their ballots on Wednesday, according to the Zimbabwe Electoral Commission.
The elections will be held under a new constitution endorsed in a referendum in March that limits the president to two five-year terms. Mugabe is allowed to seek another term because the new charter does not apply retroactively.
Last week, Mugabe had a few words for critics of the upcoming election.
In response to criticisms from the United States on his push for elections without key reforms, Mugabe said at a rally, "Keep your pink nose out of our affairs, please."
