In 2018 nearly 1.5 million Missourians voted to reform campaign finance and legislative redistricting. "Clean Missouri" passed with 62% of the vote - nearly a two-to-one margin against gerrymandering.
The amendment created the position of Nonpartisan State Demographer who would re-draw districts to be fair, contiguous, and compact. It set a $2,500 limit on campaign contributions and clamped down on unlimited lobbyist gifts.
