Election workers hand over ballot papers to elderly and disabled South African voters to cast their ballots during early voting for special groups at the Nazareth House old-age home in Johannesburg, South Africa Monday, May 5, 2014. South Africa goes to the polls on Wednesday, May 7, 2014 in elections that are likely to see the ruling African National Congress (ANC) party return to power with a smaller majority due to voters disaffected by corruption in government and economic inequality.

PRETORIA, South Africa — South African President Jacob Zuma said Monday that he anticipates an election victory this week for the ruling African National Congress, and that his government, if re-elected, will speed the provision of basic services following protests in many poor communities that complain they are sidelined.

Nearly 2,000 military personnel will assist police in ensuring security during the elections Wednesday. Officials are helping some South Africans, including the sick and the elderly, to vote early.

Zuma also said he had been unfairly labeled as corrupt because of a scandal surrounding more than $20 million in state spending on his private home. South Africa's state watchdog agency had released a report concluding that Zuma inappropriately benefited from state funding and should pay back some money for alleged security upgrades at the president's rural Nkandla residence.

The report, Zuma insisted to journalists in Johannesburg, did not conclude that he had abused government funds, despite growing public dissatisfaction over a series of scandals linked to the president. That feeling was most evident when Zuma was booed by some in the crowd at a stadium memorial in December for Nelson Mandela, South Africa's first black president.

"I don't think it is fair treatment to a citizen," the South African Press Associated quoted Zuma as saying of reports that have criticized his conduct.

While unease with Zuma has grown, it is not expected to shake core support for the ANC, which led the movement against white minority rule and has dominated politics since Mandela became president in South Africa's first all-race vote in 1994. The party has touted its record of promoting democratic freedoms and providing housing, water and electricity to millions of people, but the country struggles with high unemployment and a gulf between the poor and the wealthy.

Protests in poor communities periodically erupt. On Monday, at least 5,000 people demonstrated for better government services in the Nsuze area in KwaZulu-Natal province, blocking a road with burning tires and stones, police said. There were no reports of injuries, the South African Press Association reported.
