Johannesburg - Public Enterprises Minister Malusi Gigaba said on Sunday that the ANC would have to look at voter patterns despite winning the 2014 elections with 62.15%.
The DA got 22.23% and new-comer EFF 6.35%.
"We must look at the voting patterns of the white community, the black middle-class... and then we can do a proper analysis," said Gigaba, who was also the head of the African National Congress's elections campaign.
He said the party believed the media was against it in the run-up to the national and provincial elections.
"You campaigned hard against the ANC and we beat you."We know you never loved us. And we don't have a problem with that. Our only concern was whether the people loved and trusted us."
ANC secretary general Gwede Mantashe added that the negative campaigning of other parties hadn't worked.
Mantashe said some people were trying to find a scapegoat to blame for the party's loss of support and the loss of seats in Parliament.
"Yes we lost seats, but we have 62 plus [percent]. This has no effect on government. Losing a seat for any political party is an issue.
"Some are trying to find a scapegoat for the loss of support."
The outcome of the general election showed the ANC's support was rock-solid, he said.
Mantashe explained that genuine concerns did not include demands that government officials be removed from their jobs.
He said when communities protested to demand the removal of mayors or councillors, it did not mean it was a service delivery protest.
