Final answer:
The scenario described did not take place; Mike Johnson was not elected House Speaker after McCarthy. The theoretical process would involve internal party dynamics, majority voting, and political maneuvering among partisan alliances. The actual process involves historical precedents and the intricate balance of power within Congress.
Step-by-step explanation:
The question pertains to an event that did not actually occur; Mike Johnson was not elected House Speaker after McCarthy's ouster. This appears to be a fictional scenario or a misunderstanding of political events. The removal and replacement process for a Speaker of the House would involve internal party dynamics, majority voting within the House of Representatives, and possible swift political maneuvering among partisan alliances.
It's important to analyze historical examples to understand this process. For instance, Richard Nixon's comeback in the political scene and eventual nomination for the Republican Party was aided by the disorder within the Democratic Party and his ability to tap into his existing Republican alliances. The situation in the Senate, where a super-majority is needed for invoking cloture, showcases how minority and majority dynamics can affect legislation and leadership positions.
