To opposition figures in Africa, and in other parts of the world that lack the 240-year U.S. history of peaceful transitions of power, Trump's assertion that November's U.S. presidential election will be "rigged", and his declaration that he may not accept the outcome, are dangerous words.
"Donald Trump is a gift to all tin-pot dictators on the African continent. He is giving currency and legitimacy to rigging because if it can exist in America, it can exist anywhere," Biti said.
"He has no idea what he's talking about, absolutely no idea," said Biti, who speaks from the experience of three election defeats to Mugabe, a 92-year-old ex-guerrilla who has run Zimbabwe since independence in 1980. "It makes us cross because in Africa there's real election rigging."
Long-serving rulers who have faced U.S. criticism in the past are already using Trump's remarks to counter Washington's pro-democracy message.
