Sure. I think the lesson I learned from pursuing my Cambridge Analytica data was the fundamental necessity of the right of access. The right of access needs to be applied horizontally across the entire civil society, in both the marketplace and the government.
As to this idea that any citizen or consumer should be able to ask an entity for his or her data and be confident that it will be disclosed, what other rights do you stack on top of that? In the case of a political party, if you asked a political party to give you your voter profile, the party should be required to disclose that. If the citizen then wants to dispute or delete it, those are reasonable requests.
