I envision Constitution 2.0 to be composed of Articles. If an Article must be split into parts, each part is a Section. If a Section must be split into parts, each part is a Paragraph. For instance, 1.3.5 would be Article 1, Section 3, Paragraph 5. Maybe 1:3:5 to go for the chapter and verse connotation?
Anyhow, here are the Articles as I envision them:
Article 1: Philosophy, Authority, Amendment procedure, et cetera. a.k.a., the meta stuff.
Article 2: Citizenship, Civil Rights, Federal Voting
Article 3: Legislative Branch
Article 4: Executive Branch
Article 5: Judiciary Branch
Article 6: Relation to States
I think that everything can fit into one of those articles. If you think of something you would like that you don’t think fits in those articles, let me know! Also, think about what you would want to see in each. I’ll be doing posts on each article as time goes on.
