Explanation: After the October Revolution, the Bolshevik faction took power in a coup from the Russian provisional government organizing elections. One of their many slogans was "All power to the Soviets!", the Soviets being the local democratic workers' councils.
After dissolving the democratically elected socialist-supermajority national legislature that was returned by the recent elections, they opted to... forbid the Soviets from having new elections to maintain their power over the Soviets without the risk of the workers making the 'wrong' choices. And after that, they would dissolve the other parties and allow only the (single, picked) candidate of the Bolsheviks to run in the elections (almost always uncontested).
NO power to the Soviets!
