The turnout for Republican voters was said to be high from Tuesday's primary.
Almost 28,000 ballots were cast in the Smith County Republican Primary.
Smith County election administrators say that's more than the 2008 presidential election year.
About 2,300 ballots were cast on the Democratic side this year, too.
Party officials speculate some Democrats voted in the Republican primary so they could vote in the sheriff's race.
Smith County Republican Chairman Ashton Oravetz said voting went fairly smoothly at the polls yesterday, with no major glitches.
Twelve thousand of the ballots came from early voters.
Oravetz said the later election date helped the more conservative candidates and non incumbents.
He said the runoff election for Smith County sheriff will be interesting, since it will be in the middle of summer while many people are in and out of town.
"Obviously it's gonna be between (Chris) Green and (Larry) Smith, and it's gonna be whoever gets their voters to the polls," Oravetz said. "And who do the Bobby Garmon voters vote for ... which candidate are they more likely to go for?"
The primary runoff election is set for July 31.
