CHISINAU (Reuters) - Moldova’s presidential election looked likely to go into a run-off after preliminary results on Sunday showed that incumbent President Igor Dodon held a small lead over his main opponent Maia Sandu, but not enough to win outright in the first round. The central election commission’s data showed Dodon had 36.51% support after the commission counted 62.3% of ballots. Dodon’s main challenger, former Prime Minister Sandu, had 30.63%.
