ISTANBUL, May 14 (Reuters) - Turks voted on Sunday in one of the most consequential elections in the country's 100-year history, a contest that could end President Tayyip
Erdogan's imperious 20-year rule and reverberate well beyond Turkey's borders.
The presidential vote will decide not only who leads Turkey, a NATO-member country of 85 million, but also how it is governed, where its economy is headed amid a deep cost of living crisis, and the shape of its foreign policy.
Opinion polls have given Erdogan's main challenger, Kemal
Kilicdaroglu, who heads a six-party alliance, a slight lead, with two polls on Friday showing him above the 50% threshold needed to win outright. If neither wins more than 50% of the vote on Sunday, a runoff will be held on May 28.
