I think you’re confused by some of the punctuation.
The Constitution has in a number of places some remarkably odd placement of commas. 2A and 4A being examples.
I might have.
Please look at the structure in Post 102 and tell me where I messed up; the layout there presented seems to me to be the most natural construction (note that the comma-separated-lists are given in-line and not part of that layout).
