Cincinnati voters head to the polls tomorrow to cast ballots in the city's mayoral primary. Hamilton County Board of Elections Deputy Director Sally Krisel says it's hard to judge how busy the polls will be since there have only been two mayoral primaries in the past. The election in 2001 was on September 11th, the day of the attacks on the World Trade Center and the Pentagon.

Krisel says turnout that day was especially low, in 2005-- 21 percent of the voters came out to vote and there was no primary in 2009.

Four people are on the ballot this year, Former council member John Cranley, current Vice Mayor Roxanne Qualls, perennial candidate Jim Berns, and former council candidate Sandra Queen Noble. The polls are open tomorrow from 6:30 a.m. until 7:30 p.m. The mayor's race is the only item on the ballot.
