Cyprus holds a tightly fought presidential election on Sunday between two diplomats, each seeking to persuade undecided voters that he is the best choice to govern the European Union member."Some people are going to the polls voting for someone who is the least worse candidate, a characteristic in most elections but more so in this one," said Andreas Theophanous of the Cyprus Center for European and International Affairs.Former foreign minister Nikos Christodoulides, 49, faces 66-year-old career diplomat Andreas Mavroyiannis after last weekend's first round.
