McClure and Lynette often oppose each other, as McClure is more rational and less ideological than the First Citizen. Around 2241, some Citizens have petitioned McClure and the council to override some of the First Citizen's decisions, which created quite a stir.
In the elections that occurred after the destruction of the remnants of the United States government, Senior Council Member McClure was appointed First Citizen. Under his rule Vault City joined the NCR.
One of the threats the Chosen One can say to McClure about getting their [fake] Citizenship revoked after insulting him reads "Your powers are weak, old man. You are no match for me.", in reference to Darth Vader in Star Wars: A New Hope, in which he threatens Obi-Wan Kenobi during a lightsaber duel.
