Campaigns for office are a subset of all political campaigns.

Post-Citizens United, corporations can engage in or financially support any political campaigning they like in whatever form, as long as they don't make financial or in-kind contributions to the electoral campaigns of individual candidates. They don't need to form a PAC to do so.

Fair enough. I didn't pick up on your use of "campaign" in the broader sense.
