Moscow (CNN) Russians began voting Sunday in a presidential election widely expected to cement President Vladimir Putin's power for another six years. There is no meaningful opposition in the running, and Putin's fiercest political opponent, Alexei Navalny, has been barred from competing . Putin is seeking a fourth term as president and is already the country's longest-serving leader since the Soviet dictator Joseph Stalin. Putin cast his vote in Moscow on Sunday morning. "I am sure of the correctness of the course that I propose for the country," he said, according to RIA-Novosti news agency.
