Russians in the Far East began voting in a three-day parliamentary election in which vocal Kremlin critics have been barred from running following a historic crackdown on the opposition.

Parliamentary and local polls in the world’s largest country spread over 11 time zones began at 8 a.m. Friday. So as Muscovites prepared to go to bed, residents of the Far Eastern Chukotka and Kamchatka regions were gearing up to cast their ballots.

“Let’s go!” Ella Pamfilova, the head of the Central Election Commission, said in a live broadcast. “We are so excited!”

The run-up to the parliamentary polls has been marred by an unprecedented crackdown on Kremlin critics and independent media, with President Vladimir Putin’s top foe Alexey Navalny jailed in January and his organizations subsequently outlawed.

With many voters frustrated by falling incomes and not planning to cast their ballots, Putin urged Russians to elect a “strong” parliament.

“I’m counting on your responsible, balanced and patriotic civic position,” Putin said in a video address.

The 68-year-old Russian leader is currently isolating after the Kremlin announced this week an outbreak of coronavirus cases among his inner circle. He said Thursday that “dozens” had tested positive.

In a message from prison, Navalny called on Russians to cast aside apathy and vote pro-Kremlin candidates out of power.

“Are you not interested in trying?” he said in a message posted on Instagram, adding that even in prison he remained optimistic and urged Russians to do the same.

“I really do not think that I cannot change anything,” said the 45-year-old, who barely survived a nerve agent poisoning he has blamed on the Kremlin.

The opposition politician’s allies have been barred from running, and his team has promoted Navalny’s tactical voting project app, urging supporters to back candidates best positioned to beat Putin’s United Russia candidates.

A majority of the 225 alternative parliament candidates named by Navalny’s allies are running on the Communist Party’s list.

The media regulator has blocked dozens of websites linked to Navalny, including the tactical voting website, and has also piled pressure on Google and Apple to remove Navalny’s app from their stores.

Foreign Ministry spokesperson Maria Zakharova has claimed that developers of Navalny’s app have ties to the Pentagon, and last week Moscow summoned U.S. Ambassador John Sullivan over interference of U.S. tech giants in the polls.

Recent surveys by state-run pollster VTsIOM showed fewer than 30% of Russians planning to vote for the ruling party, down from 40% to 45% in the weeks ahead of the last parliamentary election in 2016.

But United Russia is expected to retain its two-thirds majority in the Duma, enough to change the constitution as it did last year with reforms allowing Putin to extend his rule to 2036.

The vote is being held both online and in person, in a move officials said is aimed at limiting voters’ potential exposure to the coronavirus.

The opposition says that voting over several days gives officials greater opportunities to fix elections.

The Organization for Security and Cooperation in Europe said in August that it would not be sending observers to Russia for the parliamentary election because of a limit on the number of observers imposed by Moscow.

Campaigning was lackluster, and critics said the vote was little more than a rubber-stamping of Putin’s allies.

Andrei Kolesnikov, an analyst at the Carnegie Moscow Center, said that the Kremlin needed a pliant legislature ahead of 2024 when Putin’s current term ends.

Widespread claims of voter fraud during parliamentary elections in 2011 sparked major demonstrations, but political observers were not expecting protests this time.

“Once the Duma elections are over, protests are unlikely, since the opposition and civil society are demoralized,” Kolesnikov wrote. “The regime crackdown will intensify.”

Besides United Russia, 13 more parties are running in the elections.

A total of 225 of the State Duma’s 450 members are elected through party lists, while the rest are selected in single-member districts.

More than 108 million voters are eligible to cast their ballots in Russia, and another 2 million Russians can vote abroad.

Russian passport holders from Ukraine’s two breakaway regions can take part in the vote.

Russians are also voting in local polls in dozens of regions, including regional assembly and gubernatorial elections.
