Some states in the US permanently ban felons from voting [1]. I want the eligible voting population to be all citizens over the age of 18 with no regard to history and conduct, because I favor universal suffrage and don't want governments to have leeway over who is "worthy" to vote in a democracy (yes, the US is a representative democracy). My population of eligible representative candidates in a demarchy would be the same. However, other people might not want current criminals or even former criminals to be eligible. Separately, some people might want candidates to pass an intelligence test. How could the US collectively decide the eligible population of representative candidates for a demarchy?
