Why Churchill endured as First Lord of the Admiralty

How did Winston Churchill last so long as First Lord of the Admiralty?

He was strong at administration and speeches, and his exceptional energy suited a political office that required constant activity.

Churchill's Admiralty tenure combined real strengths with the controversies that dominate many accounts of it. Administration was one of those strengths, alongside an unusual capacity to travel, speak, and press a case in public. The First Lord needed sustained activity to drive policy across a large naval institution, and Churchill did not lack energy. Those practical political skills help explain his effectiveness without implying that every naval judgment was sound.
