In July 2013, Navalny received a suspended sentence for embezzlement. Despite this, he was allowed to run for mayor in the 2013 Moscow mayoral election and came in second, with 27% of the vote, outperforming expectations but losing to incumbent mayor Sergey Sobyanin, a Putin appointee. In December 2014, Navalny received another suspended sentence for embezzlement. Both of his criminal cases were widely considered to be politically motivated and intended to bar him from running in future elections. The European Court of Human Rights (ECHR) later ruled that the cases violated Navalny's right to a fair trial, but they were never overturned. In December 2016, Navalny launched his presidential campaign for the 2018 presidential election but he was barred by Russia's Central Electoral Commission (CEC) after registering due to his prior criminal conviction and the Supreme Court of Russia rejected his appeal. In 2017, the CEC stated that he would not be eligible to run for president until after 2028. In 2018, he initiated Smart Voting, a tactical voting strategy intended to consolidate the votes of those who oppose United Russia, in order to deprive them of seats in elections.
