Missouri Proposition C

---is on its way to passage.

With about 70 percent of the vote counted late Tuesday, nearly three-quarters of voters had supported the measure.

Tuesday's vote approving the ballot measure, known as Proposition C, was seen as largely symbolic because federal law generally trumps state law. But it was also seen as a sign of growing voter disillusionment with federal policies and a show of strength by conservatives and the tea party movement.
