What’s Happening

Russia's State Duma election is scheduled for September 2026, and the ruling United Russia party has already assembled a high-profile slate. At its pre-election congress on June 28, party chairman and former president Dmitry Medvedev unveiled lead candidates including an injured Ukraine war veteran, a television war correspondent, the foreign minister, and the mayor of Moscow—a lineup built to fuse patriotic wartime symbolism with establishment weight. The question of whether United Russia will win 355 or more seats in the next Russian State Duma election hinges on a supermajority threshold: 355 of 450 seats would exceed the party's already dominant 324-seat bloc from the 2021 vote, a bar even a tightly managed contest may struggle to clear.

The pre-election period has been marked by an intensifying crackdown. On August 10, Russia's Supreme Court removed the anti-war Yabloko party from the ballot after it began polling at 6%, ruling in favor of a suit filed by the Rodina party. Days later, on August 18, a court sentenced opposition politician Lev Shlosberg to 11 years and one month in prison for opposing the war in Ukraine. These moves narrow the field ahead of the vote, but they also underscore that whether United Russia wins 355 or more seats depends less on organic support than on administrative control of who appears on ballots.

The election unfolds amid deep war fatigue. CSIS estimates 450,000 Russian troop deaths since the February 2022 invasion, and one Russian economist noted Putin is struggling to project control. Ukraine's intelligence chief Kyrylo Budanov said on September 1 that Moscow will likely sustain drone attacks through the vote to show a "picture of victory." Whether United Russia wins 355 or more seats will test how far managed legislation can outrun public discontent. [Newsweek, Aug 21]
