Are Zimbabwe Voters Worried About Mugabe, Tsvangirai Health Problems?Some Zimbabweans say they are not concerned about President Robert Mugabe and MDC-T leader Morgan Tsvangirai's illnesses in the run up to the 2018 presidential election. Responding to a snap informal poll on VOA Studio 7 Twitter on whether they are worried about the two’s health issues, 42 percent of the respondents expressed concern while 47 percent said they are not worried at all. Eleven percent of the 60 respondents out of 559 who saw the tweet, indicated that they were not sure about the presidential candidates' ill health. The informal poll, which does not necessarily represent the views of all Zimbabweans as most of them are not on Twitter, was conducted last week. Mr. Mugabe has travelled three times this year to Singapore to seek medical care while Tsvangirai, who has cancer, is being taken care of by South African health experts. The two bitter rivals are preparing for the crucial 2018 presidential election as the economic crisis continues in Zimbabwe. President Mugabe will be 94 when elections are conducted next year, making him the oldest-ever person in the world to take part in such a poll. Tsvangirai has been trying, in vain, to unseat Mr. Mugabe since the formation of the Movement for Democratic Change in 1999. He beat him in a presidential election in 2008 but fell short of the needed votes to form a government. Tsvangirai withdrew from a presidential re-run due to politically-motivated violence, which gripped the country before the election.
