Jefferson City, Mo. – About 23 percent of Missouri voters turned out for Tuesday's primary elections.
The biggest draw was Proposition C. Nearly 939,000 people cast ballots on the measure saying government cannot require people to have health insurance nor penalize those who do not. It passed with 71 percent of the vote.
The Missouri law conflicts with a federal law requiring most Americans to have health insurance or start facing penalties in 2014.
Voter turnout was the highest for an August election since 2004, when 35 percent cast ballots on a measure banning same-sex marriage.
The second biggest attraction on this year's ballot was Missouri's U.S. Senate race. Congressman Roy Blunt won the Republican nomination while Secretary of State Robin Carnahan won the Democratic primary.
