Anti-electoralism is common on the left, be it the libertarian or authoritarian parts, though I’ve noticed that people with revolutionary tendencies tend to be the most anti-electoral.

Tankies are usually anti-electoral for the same reason most revolutionary leftists are, be it anarchists or state communists, since they don’t see electoral systems as a means to free the workers and/or other oppressed groups.

Granted, the more libertarian left opposes electoralism for many more reasons beyond seeing it as an invalid means to their end. And everyone here supports some system of self determination and organization, just not your state representative “democracy”

Tankies are 'against electoralism' in the way they're against everything else - ie only when it isn't controlled wholly by their preferred party. They sing the praises of elections in which only the Party's candidates are allowed to run as the peak of democracy.
