C-SPAN's state-of-the-art tour bus attracted some of the state's leading politicians when it parked in front of the State Capitol on Tuesday.

Republican Secretary of State Tom Schedler discussed election security, partisan politics and voter turnout issues during a live interview with C-SPAN's “Washington Journal” morning program.

Attorney General Jeff Landry talked coastal erosion, opioids and crime.

And House Speaker Taylor Barras, R-New Iberia, said he thinks that the state's fiscal woes are the biggest issue facing Louisiana today.

"I think just politics in general have reached an all-time low across the country," Schedler said of disaffected and unenthused voters. 

Schedler, who served in the state Senate from 1996 to 2008, said members worked across the aisle and weren't afraid to compromise.

"That's turned into a very dirty word now," he said, adding that he thinks the Louisiana Legislature is beginning to become more partisan and resemble Congress.

Landry, a staunch supporter of President Donald Trump, was asked about the Trump administration's push to withdraw the country from the Paris Climate Accord.

"The problems that Louisiana faces in regards to its coastal erosion problem is mainly attributed to the Corps of Engineers and the national policy that was designed to protect the Mississippi River in its current state," Landry said. "Louisiana's coastal problem has nothing to do with climate change."

Syria this week signed onto the Paris agreement, leaving the United States as the only country to reject it. 

The pact's goal is to fight global warming by reducing greenhouse gas emissions, which scientists say will lead to rising sea levels, dangerous storms and other catastrophic weather events.

Landry also addressed his repeated run-ins with Gov. John Bel Edwards, a Democrat. Landry attributed their disagreements are due to differing interpretations of the law.

"We have had to go to court on numerous occasions, and it's unfortunate each time," he said. "I would think that based upon (our) winning record, we have got a pretty good idea what our constitution says here in Louisiana. I'm pretty sure the governor takes disagreement to that."

Between interviews, views of the State Capitol were shown to C-SPAN's national audience. A dedicated line also was set up for Louisiana viewers to get priority when they called in while Louisiana politicians were on air.

C-SPAN has embarked on a tour of all 50 state capitals in the network's customized 45-foot motor coach, which includes a mobile studio and interactive elements for kids. 

Other scheduled stops on its Baton Rouge visit include Lee High School, Broadmoor High and Tara High.

Schedler, who co-chairs the National Association of Secretaries of State's Elections Committee, said that Louisiana's votes are secure because the state relies on a "top down" approach to running elections. All voter machines are handled at the state level and operate on the same system. In some states, machines and tallies are handled at the local level.

"It's a very closed system," he said of Louisiana's approach. "I think that gives us a more secure model."

Schedler had been scheduled to testify during a congressional hearing this week on elections, but the hearing has been postponed.

Schedler, who has long advocated for fewer special elections, said he thinks Louisiana's busy election schedule in the past two years has given him ammunition to make a case to the Louisiana Legislature during next year's session.

"I've been a big proponent for several years of a temporary appointment process," he said, noting that Louisiana has had an interim treasurer since John Kennedy joined the U.S. Senate in January but will hold a special election this month to fill the spot for the next two years.

Schedler has predicted during the show that turnout in the treasurer's race will be below 15 percent. He said it costs the state the same amount — about $6 million — every time it runs a statewide election, no matter how many people vote.
