Papi Mazibuko, a 50-year-old library assistant, decided it was time to switch teams and vote for the Democratic Alliance, the leading opposition party in the national elections in South Africa on Wednesday.
Houses on his street in the township of Evaton, south of Johannesburg, had been without power for two and a half years because of a broken transformer. The government, led by the African National Congress, or A.N.C., failed to fix it.
The neighboring municipality, run by the Democratic Alliance, had a good record of delivering basic utilities. So Mr. Mazibuko rallied neighbors to a campaign event last year that featured John Steenhuisen, the party’s leader, who has been met with skepticism by some Black voters because he is white.
“We want service delivery,” said Mr. Mazibuko, who had been an A.N.C. member since his teens. He added that even if “a white man can deliver, then so be it.”
Opposition parties see this year as their best chance to break the political dominance of the A.N.C., which has comfortably won all six national elections since the first democratic vote 30 years ago. South Africa’s opposition has long failed to inspire voters, political analysts say.
This year, though, many polls predict that the A.N.C. will fall below 50 percent of the national vote. A record 51 opposition parties on the national ballot are trying to sell South Africans on the idea that the country would be better off without the A.N.C. in charge.
The options are diverse: from the center-right Democratic Alliance, which wants to scrap economic policies that give preferences to nonwhite South Africans, to the left-wing Economic Freedom Fighters, the third-largest party, which advocates an aggressive redistribution of wealth to the nation’s Black majority.
