Participation in bourgeois elections is to delegitimize the system (such as pointing out Dem/Rep collusion to kick them off the balot in Georgia), and advertise their platform.
Marxists believe revolution is necessary and electoralism is a sham.
They aren’t running for a revolution, if they were, they wouldn’t be on the ballot for an election.
It’s all performative nonsense.
