Municipal elections in Warren County April 4 might be decided by as few as 10 percent of registered voters.That’s the average turnout predicted by County Clerk Barb Daly for voting precincts across the county. Some municipalities could put up higher participation numbers, such as Warrenton, which has a contested mayor’s seat on the ballot.There are about 22,000 registered voters in the county.April elections generally aren’t well-attended, Daly said. The turnout for 2016 was 20 percent, 2015 was 8.82 percent and 2014 had 15 percent turnout, she added.Absentee ballot requests can be an indicator for what broader participation numbers will look like. Daly said, so far, her office has received 120 such requests, a relatively low number.One reason voter participation is expected to be lower than in recent years is that there are few local ballot measures. Voters in the Gasconade School District in southwestern Warren County will be asked to vote on a 50-cent tax levy increase, but residents in the rest of the county will see only names — no propositions — on the ballots.Voters are required to show some form of identification at the polls, including a driver’s license or voter registration card. Stricter identification requirements approved last year won’t apply to this election. They are scheduled to go into effect June 1.Polling places will be open 6 a.m. to 7 p.m. Tuesday.The deadline to request mailed absentee ballots has passed. Early voting in person at the county administration building can be done until Monday, April 3, Daly said.Races in reviewIn Warrenton, the offices of mayor and one alderman from each of the city’s three wards are up for election.
