It's just desperately sad to see people treating these laughable 'results' even semi-seriously. Even the old Commie hacks during the Cold War didn't pretend, as a rule, that Eastern Bloc elections were 'real'; they made other excuses. Sad, sad, sad.
They measured popular participation and mobilization in the symbolic excercise - Samantha Lomb wrote an interesting book on Stalin's Constitutiom of 1936 and the participatory (but not democratic) exercises around it. Open access:
