Electing a new state treasurer is at the top of Louisiana ballots Saturday when polls open at 7 a.m.

Voting will be allowed until 8 p.m.

Most parishes will have only the state treasurer and three constitutional amendments to consider.

But some voters will be choosing a Public Service Commissioner. Others have judges and local officials on the ballot. Two Louisiana House Districts are in the contest.

“We anticipate turnout on Saturday, unfortunately, to be very low based on historical data and early voting statistics,” said Secretary of State Tom Schedler. “I have indicated that I’ll happily eat crow if Louisiana’s voters prove me wrong and I hope they do.”

He expects about 15 percent of the voters – less than a half million out of the 2.7 million registered – to go to the polls. A week of early voting collected half the number of ballots as the December 2016 runoff for a U.S. Senate seat, another low participation election with 29 percent turnout.

Statewide elections cost taxpayers about $6 million to conduct.

Though the state treasurer is fourth in the gubernatorial line of succession, the race to fill the remaining two years of John N. Kennedy’s term has been quiet. No one candidate is thought the favorite.

Kennedy resigned in January to join the Senate, necessitating this special election.

A treasurer is essentially the state’s banker and chairs the State Bond Commission, which oversees loans.

The candidates are former Commissioner of Administration Angele Davis, R-Baton Rouge; New Orleans attorney Derrick Edwards, D-New Orleans; businessman Terry Hughesm R-Lafayette; mail carrier Joseph D. Little, a Libertarian from Ponchatoula; state Sen. Neil Riser, R-Columbia; and former state Rep. John Schroder, R-Covington.

A Nov. 18 runoff is scheduled between the top two vote-getters, if no one candidate wins a majority.

Voters in 13 parishes, including parts of Baton Rouge, Acadiana, Houma and Morgan City, also will be deciding who will fill out the rest of Scott Angelle’s term on the Public Service Commission. Angelle resigned in May to join the Trump administration.

Three Republicans – Interim PSC Commissioner Damon Baldone, of Houma; former state Rep. Lenar Whitney, of Houma; and Dr. Craig Greene, of Baton Rouge – are competing for the 2nd PSC District’s 610,334 registered voters.

The five elected commissioners set the rates utilities charge for electricity and telecommunications companies and transportation within the borders of the state, such as home movers and cabbies.

Voters across the state also are being asked to determine whether to add to the state Constitution a property tax exemption for projects under construction.

The second proposition would exempt the surviving spouses of first responders who died while on duty from property taxes on the home of the deceased.

And the third constitutional amendment asks voters to decide if the proceeds from any future hike in the state gas tax should go into a fund dedicated to construction of roads and bridges.

The amendments must win the support of a majority of those voting Saturday to be added to the state’s Constitution.

Residents of East Baton Rouge Parish School Board District 7, which includes LSU and stretches east to Kenilworth Parkway, are having a special election to pick who will replace Barbara Freiberg as their public school representative. Freiberg, after six years in the job, joined the Metro Council in December.

Also in Baton Rouge, six candidates are running for a City Court judge seat previously held by Suzan Ponder, who retired over the summer.

The Covington-based district includes much of western St. Tammany, also including Madisonville and parts of Folsom.

Three candidates are in contention for a judge seat on the 18th Judicial District Court to replaced Judge James Best, who retired earlier this year. This seat covers 22 precincts in Pointe Coupee Parish and two precincts in West Baton Rouge Parish.

Denham Springs voters will choose from six candidates for an at-large City Council seat.

Livingston Parish voters will consider a schools property tax renewal, while Gonzales residents will vote on a half-cent sales tax for fire and police protection, as well as building a new civic center and community youth center.

In parts of Iberville, Ascension and St. James parishes, 25,810 voters in the predominantly African-American Louisiana House District 58 are choosing a state representative among four Democrats.

Two of the candidates – Miguel Aubert and Ken Brass – hail from Vacherie at the southern tip of district. Adrienne Ricard Conish and Alsie Dunbar, live in Gonzales, on the northern end. The race is to fill the remaining two years of Ed Price’s term. He was elected in the spring to the state Senate.

Four St. Tammany Parish residents are running to fill out the remaining two years of Schroder’s term in the Louisiana House. He resigned in June to run for treasurer.

Three Republicans — Rob Maness, Casey Revere and Mark Wright — but also a candidate with no party affiliation who until recently was registered as a Democrat, Lisa Condrey Ward, are running for House District 77.

New Orleans is electing a mayor and a city council.
