for the question of where do i find the rules IN DETAIL for being voted in,... in the "other box" in the primary election up-coming, also known as "being written in" in the "write-in ballot" I need all sections of law, rules and detail for this aspect. AND what exceptions and exemptions exist. I have tried all search engines... Charles
