You will never make gains against the ground troops because they legitimately do not care. At all.

Those left in love the power and are there for the career. If they have to step on your neck to advance, so be it.

The only way forward is attacking the power structure directly at the points of fault; the elected and commissioned officials. Antfi style protests right outside their front door, constantly harassing them in bars and bathrooms, and generally making them feel unsafe.
