Former City Councilman Troy Carter and state Rep. Jeff Arnold are going to a run-off for the Senate District 7 seat on the West Bank.

With all the votes counted, Carter led the four-person field with 37 percent of the vote. Arnold was close behind with 33 percent of the vote. Orleans Parish School Board member Leslie Ellison was in third with 15 percent of the vote and businessman Roy Glapion had 14 percent of the vote.

About 7,700 votes were cast for Carter and 6,860 were cast for Arnold.

The district is on the West Bank and includes portions of Orleans, Jefferson and Plaquemines parishes.

The seat became a free-for-all just before this year’s qualifying period, when Sen. David Heitmeier announced he would not seek a third term so he could focus on his health. Heitmeier was first elected after his brother, Francis Heitmeier, was prevented for running for a fifth term due to term limits.

The race pitted well-known political names against each other to represent a district that includes parts of the West Bank of Orleans, Jefferson and Plaquemines parishes.

Arnold is currently the longest-serving member of the state House and the son of Tom Arnold, the former assessor. Carter is a former city councilman and state representative who had run for both mayor and U.S. Congress in the past. Glapion’s father was a city councilman in the 1990s.

Much of the race has focused on infrastructure needs in Algiers as well as the fate of Federal City, the former navy base in Algiers that officials have been working to redevelop.

Throughout the race, Arnold focused on his experience and seniority while Glapion took the opposite tact, noting his status as a relative political outsider. Carter touched on his experience but also sought to cast himself as a change for the district. Ellison has focused on education in her campaign.
