Modifies requirements for votes required to pass constitutional amendments

HJR 80 changes how constitutional amendments are proposed and approved in Missouri. It requires initiative petitions for constitutional changes to collect signatures from 8% of voters in two-thirds of congressional districts (plus other thresholds), bans foreign governments or agents from funding or sponsoring initiatives, and mandates that constitutional amendments must win majority votes statewide *and* in a majority of counties to pass. These rules directly affect citizens proposing changes, the Secretary of State (who administers petitions), and the legislature (which faces a two-year waiting period before repealing laws passed via initiative). The bill modifies procedural requirements for constitutional amendments, not regular laws.
