Stalinist monarchy!
Yeah definitely not. Somehow it just sounded like the most amusing thing to argue for as long as no one is actually going to be subjected to the living hell that would be.
Stalinism would presumably include but not be limited to intense propaganda campaigns, fast industrialization with a focus on heavy industry and munitions, large-scale population transfers based often on ethnic paranoia, an elaborate system of prison camps and political terror, strict censorship, and a well-developed official patriotism pervasive in art and culture. And periodic political purges based around show trials and fabricated crimes. Oh, and manmade famines, concealed mass executions, etc.
The options on the poll don't seem very... balanced. What about other possibilities? What about the shades within them (i.e. a constitutional monarchy vs. an absolute monarchy)? And how many people are going to honestly vote for a Stalinist system knowing what we know now about what he did?
Also, poor Prokofiev. His funeral was hardly noticed because he was unlucky enough to die the same day as Stalin.
