A communications plan in the PM's eyes is the most critical piece. Who gets to see the project's status? The media, nor the Democrats could comprehend that their exclusion of receiving project status was based on who the stakeholders were, and the media and DNC were not stakeholders. They were a risk and an impediment and Trump mitigated the risk by taking his message directly to the people from his Twitter account. His Stakeholders.
Your professional experience differs significantly from mine. In my projects, everyone gets to see the project status- for better or worse- on a Project, Excel/Sharepoint or BI dashboard or even Post It Note whiteboard for everyone to see- at their convenience, not mine.
I've always found transparency to be critical. I never had a situation where keeping information from a stakeholder- no matter how adversarial- worked to make the project more successful.
