HARARE - President Emmerson Mnangagwa registered on Thursday for Zimbabwe’s first national elections of the post-Mugabe era, with his main rival Nelson Chamisa hoping to rally younger voters against the generation that won independence.

Zimbabwe’s Mnangagwa, main rival sign up for first post-Mugabe election Western governments and investors will be closely watching the July 30 presidential and parliamentary ballots, for which monitors got clearance to deploy for the first time since 2002.

Mnangagwa and Chamisa, who also signed up on Thursday, are both campaigning on a pledge to revive an economy crippled by a legacy of often violent seizures of land from white commercial farmers and a black economic empowerment drive that targeted foreign-owned businesses.

Those policies were cornerstones of Robert Mugabe’s near four-decade rule, which ended in November after a de facto military coup that transferred power to 75-year-old Mnangagwa, his loyal acolyte for nearly 50 years.

The ruling ZANU-PF says Zimbabwe is at a critical stage of transition requiring an experienced politician like Mnangagwa.

Chamisa, the 40-year-old leader of the opposition Movement for Democratic Change (MDC), says the president is equally to blame for the country’s economic troubles, since he served in each of Mugabe’s governments since independence in 1980.

Both arguments appear to have struck chords among the 5.4 million-strong electorate, 60 percent of whom are under 40.

While Zimbabwe lacks a reliable polling system, an unofficial survey released last week in its second city Bulawayo by the Mass Public Opinion Institute put Mnangagwa on 42 percent and Chamisa on 31 percent, while 25 percent declined to disclose a preference.

Crucially, Mnangagwa enjoys the backing of the army, which analysts say remains averse to any leader who lacks a pedigree from the liberation war against white rule.
