The race for the City of Johannesburg is on with a poll this week indicating that the Democratic Alliance (DA) has edged ahead of the African National Congress (ANC).

The poll, commissioned by eNCA and undertaken by Ipsos, monitored voting trends ahead of the August 3 local government elections in Tshwane, Johannesburg and Nelson Mandela Bay in the Eastern Cape.

According to latest numbers, the DA was ahead of the ANC by four points with 36% of people saying they would vote for the party in the City of Johannesburg. The Economic Freedom Fighters (EFF) was far behind with just 9% indicating they would support the party.

The DA has marginally led the polls in Johannesburg since it began campaigning eight weeks ago. Meanwhile, ANC mayoral candidate Parks Tau marginally leads popularity over the DA's Herman Mashaba with a 5.8 point rating over Mashaba's 5.4.

The DA has maintained a commanding lead in Tshwane since campaigning kicked off, with 41% of people saying they would prefer the party. The ANC received 26% and the EFF 11%.

In terms of popularity, the DA's Solly Msinga has outdone the ANC's Thoko Didiza consistently with a 6.1 rating over Didiza's dismal 4.7 this week.

The DA has also edged out the ANC at Nelson Mandela Bay with 44% over the ANC's 30%. The EFF struggled in the Eastern Cape with just 6%.

Leadership popularity was fairly close with the ANC's Danny Jordan at 5.3 and the DA's Athol Trollip ahead with a 6.2 rating.
