• Even though it's the most recent state to join the off-year election trend, Louisiana's elections have been off-kilter since the 1800s. "We used to have our election in the early spring of the even-numbered year of a presidential race," said Mike Henderson, director of Louisiana State University's Public Policy Research Lab.
• Then, in the 1970s, one of the state's most controversial political figures, Gov. Edwin Edwards, a Democrat (who served four nonconsecutive terms as governor and also federal prison time for corruption), saw other traditionally blue Southern states turning red during President Nixon's Republican administration and called for a constitutional convention to, among other things, move elections to odd years.

Running elections every single year (federal in even years, state in odd) can cost a lot more money. Most election officials couldn't nail down the exact dollar amount for us, but in Kentucky, lawmakers who want to realign the elections calendar claim that doing so would save the state and county coffers about $15.5 million every four years.

An official with the Virginia Department of Elections said the main cost is staff time. Staff members are almost always running the current election or preparing for the next imminent election.

That means making changes in how an election is run, upgrading equipment or adjusting to changes in state code all have to happen in a very tight time frame.

"There's no downtime," said Virginia Deputy Commissioner Jessica Bowman. "That's what our cost is."

In New Jersey, Bob Giles, the director of the New Jersey Division of Elections, said that this kind of regularity can be beneficial too. The frequency of races means the state's 26,000 poll workers stay familiar with the Election Day process and how voting machines work.

"The same with voters. They understand that every June there is a primary, every November there's an election," Giles said. "It's just a matter of who is on the ballot."

But that doesn't necessarily translate into voter turnout. In Virginia, voters are likely to skip off-year elections, especially in years like 2019, when the focus is the legislature, not the governor.

Just 29% of Virginia voters cast their ballot in the last such election, in 2015, compared with 72% in the presidential election the following year. That means less than half the number of voters came out to vote in 2015 as did in 2016.

For those same years in Kentucky, about 31% of the electorate made it out to the polls in 2015. In 2016, turnout was up to 59%.

Similarly, in New Jersey in 2016, 68% of registered voters came to the polls. A year later, in the 2017 gubernatorial race, just 39% of voters cast a ballot.

Election experts have speculated that staying in an odd-year election format has benefited Democrats in Kentucky, who until recently have stayed in power in the state while voters have long voted for Republicans at the federal level.

The last time Kentucky voted to send a Democrat to the U.S. Senate was in 1992. The last time the state voted for a Democratic presidential candidate was Bill Clinton in 1996.

Meanwhile, Democrats continued to dominate state government until recently. Current Gov. Matt Bevin is only the third Republican governor of the state since World War II and is running a tough reelection campaign against the state's Democratic attorney general, Andy Beshear.

The same is true in Louisiana, where odd-year elections have allowed conservative Democrats to stay relevant as they have faded away throughout the region. Louisiana is currently the only state in the deep South with a Democratic governor.

In Virginia, as the national Democratic Party tilted to the left with FDR, the state's conservative Democratic lawmakers benefited from not sharing the ticket in presidential elections.

Republican President Dwight Eisenhower easily carried Virginia in 1952 and 1956, but Republicans didn't elect a governor until 1969 with Linwood Holton. The party didn't control a chamber of the legislature until it won the state Senate in 1998 in a special election.

Today, though, political analysts broadly agree that the current schedule benefits Virginia Republicans because their base votes more reliably than blocs backing Democrats.

"The people who are most motivated in the electorate tend to be older," Larry Sabato, the director of the University of Virginia's Center for Politics, said. "They tend to be whiter, and they tend to be Republican."

There has been little appetite in changing Virginia's calendar, which would require a constitutional amendment.

A 2015 bill by Democratic Delegate Marcus Simon that would have tracked Virginia onto the federal calendar didn't even make it to the floor. Sabato said politicians in the state are unlikely to change anytime soon. "There's one thing they know for sure: They were elected under the current rules."

The conventional wisdom — often repeated in legislative circles — is that Virginia does not want to moor its ship to the federal man-of-war.

Lawmakers in Kentucky have made more room for the discussion. Several bills over the past few years have been proposed to move the gubernatorial election to even years. (One complicating factor is that one governor would serve five years, instead of four, to realign the elections.)

Opponents have called those bills a ploy to bring Kentucky's down-ballot races — which until lately favored Democrats — in line with federal elections, where the Kentucky electorate has skewed Republican in recent decades.

Joshua Douglas, an election law professor at the University of Kentucky, said the move could increase voter turnout for state elections, which have been poorly attended in recent years.

"I think [poor election turnout] is bad for democracy. Anything we can do to increase turnout is a good thing in my view," Douglas said.

According to him, moving the state contests to presidential election years might make voters more informed and less fatigued.

"My view is that if we do it all at once when people are talking about policy and political issues, then you're going to have higher turnout with a more informed political electorate as well," Douglas added. "They're not feeling like they're coming out to vote so often that it's hard to keep up."
