Isn't the Incan Federal Technate somewhat a democracy? They elect their leaders, right?
Pretty much, they wouldn't be able to choose their leaders otherwise, but the candidates have to fulfill certain "requirements" to be eligible to run such as specific level of education and previous occupations among other things unlike the British Federation where practically everyone can run. Technocrat nations generally follow either this form or a clan-based system (with each clan focusing on specific occupation) or a combination of both.
