The two main opposition candidates will try to beat the odds, media blackouts and public mudslinging as they face the vote Sunday that pits them against autocratic Prime Minister Aleksandar Vucic. No easy task when a recent survey by social research group BIRODI showed that Vucic has received more than 120 times as much news coverage as Jankovic and Jeremic combined during the election campaign. Jankovic, who won international praise for his work as ombudsman, was flatly described by a Belgrade tabloid newspaper as the "killer" of a friend who committed suicide in 1993. Vucic has denied the accusations of running a dirty campaign, saying the only platform opposition candidates have is "hatred for Vucic." Human rights champion Jankovic is supported by pro-Western liberal voters, while former Serbian Foreign Minister Jeremic has the support of more conservative and nationalist groups. Jeremic said one example of the media bias was when Vucic's populist Serbian Progressive Party accused Jeremic's wife, a well-known former state TV anchor, of being the boss of all the narcotics cartels in Serbia.
