2020 Chama Cha Mapinduzi presidential primaries

The 2020 Chama Cha Mapinduzi presidential primaries took place in July 2020. Incumbent president and 2015 nominee, John Magufuli ran unopposed for his second term for the President of Tanzania and so there was no primary vote for the Union presidency position. However, Zanzibar president Ali Mohamed Shein is ineligible for re-election due to term limits and a primary was held to determine the Zanzibar presidential nominee. The winners of the primary are the CCM candidates for the 2020 Tanzanian general election and the 2020 Zanzibari general election.
