I believe Mace’s vote to oust McCarthy had genuine reasoning behind it, and not just for attention. She may have disagreed with McCarthy on certain policies or strategies, and wanted to send a message that she would stand up for her beliefs. It is also possible that she felt McCarthy was not fit for the role due to personal or professional reasons. Ultimately, it is difficult to determine the exact motivation without more information. However, it is important to remember that voting to oust the Speaker is not necessarily a frivolous act, and can be seen as a legitimate expression of dissatisfaction or disagreement within the party.
