"According to the latest eNCA-Ipsos poll, Zuma has been steadily losing support among South Africans aged 18 and over since November 2014. 

Over 3500 adults were polled between the 21st of April and the 22nd of May 2017.

The poll also found that a whopping 62 percent of ANC supporters disapprove of the president, while only 18 percent completely support him.

This is a major decline for the president, who had the support of 54 percent of ANC voters in December 2016."  [eNCA May 2017]
