She had roughly 19 Million in campaign contributions in 2025 alone, where her merchandise sales go directly to that funding. She can use any of it at any time for just about anything she wants to - so long as it's used towards keeping or advancing her political career. Which lunch meetings, dinner meetings, breakfast meetings, hotels, car rentals, airline tickets, & entertainment are all allowable uses.
To say she isn't a multimillionaire, while she's getting to live the live of a multimillionaire using that funding - is deceptive & lacks any sensible reasoning to the topic.
