I liked your comment. You said in words my vague thoughts on it:

The masses in the US already see politics mostly through the electoral struggle. For most, it's their only political terrain. We'd love for the masses to be at a higher subjective level in the States, but you can't force such subjective changes of the masses.

So work earnestly with the masses in the terrain but always be pointing out the contradictions and limitations as you mentioned.

Through struggle, and with Communists pointing out these limitations while working with the masses, not scolding them, these contradictions become lived by the masses. The limitations are internalized and understood, and the terrain can shift. The struggle can advance, but the contradiction has to be lived and understood.

Only struggle, or practice, by the masses can actually advance the dialectic.
