I think Cummings is a target because of his privileged position without accountability. He is portrayed in the press as arrogant, and dismissing any hint of criticism.
Arrogance can be such a weakness, especially when considered by that person to be a strength. There are countless examples of politicians who have fallen as a result of arrogance, and more recently, those senior advisers, who simply don't think guidance applies to them.
With not much else going on apart from the obvious......he's a prime target. If he hangs on then all Boris will get is this.
