I assume those are supposed to be necessary rather than sufficient conditions, because my immediate thoughts are:
1: Why adults? Why citizen? How do you define each?
2: Why make them equal when you just excluded minors and non-citizens entirely — e.g. you could make it so 13-18 year olds get counted as (years less than 18)/5 of a vote, why is that bad?
3: why is that important, why not require passing a basic civics qualification?
Meta: when non-white people were disenfranchised, were they also treated as “not people”? If so, what other categories currently considered “not people” should in future be treated as people? (If any)

There is a worlwide consensus about that people from other nations are not allowed to participate in elections of the government of a country. We would need to change the legal definition of a sovereign country for allowing it, and the benefits are unclear (to start, the president of all small and middle sized countries would be chinese).
There is a worldwide consensus also about that laws have to treat minors in a different way than adults. More indulgent. They have different rights and duties. Minors are expected to commit mistakes.
Allowing a toddler to vote for a party would imply explaining first what means terms like "left", "my left, not your left", "rigth", "communism", "liberalism", "populism" or "fascism", when they should be crashing windows with baseball balls instead. This would hit close to adoctrinating boys and girls and forcing them to choose one side (and deal with the unavoidable consequences in a yet enough confuse and complex phase of their lives).

Lets people decide with their vote if is a politician or a clown. This is the purpose of voting. If the semi-automatic lonely boy is democratically elected by the majority, people has spoken, and I'm fine with that.
