The "beauty contest" nature of Missouri's presidential primary earlier this week may have contributed to the lowest turnout for a presidential primary in the state's history.
Just 8 percent of the state's registered voters cast ballots in the Republican and Democratic primaries. About 252,000 people voted in the GOP race, and 73,000 in the Democratic primary.
