Organizers said Monday they were pleased with the turnout of about 700 conservatives, many of them Tea Party members, from around the nation who rallied Saturday in a pasture just north of Jefferson City.
Those attending the Rally for Common Sense parked their cars in a field used to grow corn last year to hear former presidential candidate Herman Cain urge them to make their voices heard by voting in November.
In 90-degree heat, most of the crowd headed away from the main stage to the shade of nearby trees during a full day of speeches and musical entertainment.
Cain has suspended his campaign for the Republican nomination for president.
"But I haven't given up," Cain said. "Conservative voices still need to be heard. The election process is what it is. Liberals hope conservatives will give up and won't vote.
"If you stay home, that's the same as a vote for Obama, and that would mean four more years of nightmare," Cain told a cheering audience.
