No, my point is that the rules that always apply on Earth, in the real world, don't always apply on another world, in the world of fiction. In the world of fiction, there are more often than not, aliens that are basically humans. Or in the real world, there are different rules of law and government across each country. Some are similar, other are different. The idea in the GFFA, is that children are not as incompetent. They are tasked with making decisions that adults would make and show an ability to do so, despite their age. According to Padme, she was involved in a program that taught governmental practices and that it gave her the credentials to run for the office of monarch on Naboo. She had won because her campaign had resounded with the people and they trusted her to enact those policies. She had acquitted herself well against her opponent in debates and showed a maturity and grace that was becoming of someone her age. That doesn't make the people of Naboo dumb, just culturally from us. And as she would go on to prove, she was capable of making the hard decisions and freed her people from an invasion force, a task that her opponent wouldn't have been able to have achieve due to their ignorance and unwillingness to take the path that she did. Any doubts that might have been had were quickly swept away. And as to Jar Jar, she had appointed him to be the Gungan Representative in the Senate. A move that was probably welcomed since his clumsiness was getting him into trouble. But clumsiness aside, Jar Jar was instrumental in the liberation of Naboo and the uniting of the Naboo and the Gungans. That makes his appointment acceptable. Not to mention she surrounded herself with advisers who were well suited to the task, like Bibble. As to the constitution of Naboo, it isn't like Congress or Parliament. The rules would be different based on what was drafted long ago. Among other things, that the monarchy would last up to two four year terms and not anymore than that, much like the 22nd Amendment which put term limits on presidencies. Lucas went this route to set up the notion of a noble person who gives up their power, for the good of the people, rather than like Palpatine who keeps it for himself and bends the rules to his advantage. Hence the exposition about Padme's political career being a parallel for Palpatine's ascendancy.
