Rep. Seth Moulton is apparently riding high after a candidate he endorsed in a key Kentucky race won her Democratic primary Tuesday.

The Massachusetts Democrat added three more military veteran candidates to his Serve America leadership PAC endorsement list on Wednesday: a former Obama administration official in New Hampshire, a state senator in Nevada, and a retired Navy commander who was one of the first women in the Navy’s nuclear program.

• Maura Sullivan, a Marine Corps veteran who served in the Iraq war, is running in a crowded Democratic field for the open seat in New Hampshire’s 1st District. After her service, she was appointed as an assistant secretary of Veterans Affairs by President Barack Obama.

“I am really proud to have the support of my fellow Marine and Iraq veteran,” Sullivan said of Moulton’s endorsement in a statement Wednesday. “I respect his leadership, commitment to service, to our country and to working toward something much bigger than ourselves.”

• Moulton highlighted Pat Spearman’s track record on the local economy and environmental issues in Nevada and her leadership among the LGBTQ community in her campaign for the state’s 4th District.

“As the first lesbian member of the Nevada State Legislature, Dr. Pat Spearman paved the way for others to answer the call to serve,” Moulton said. “In the State Senate, Pat focused on job creation by diversifying Nevada’s renewable energy sources, a forward-looking approach that addresses the challenges of the modern economy.”

“Pat will bring that same innovative thinking with her to Washington,” he said.

Gonzales rates the race for the open seat Likely Democratic.

• In the race for Virginia’s 2nd District seat, Moulton endorsed Elaine Luria, a retired Navy commander who served as a surface warfare officer, serving at sea on six different ships. The Naval Academy graduate was one of the first women to serve her entire Navy career on combat ships.

“Elaine Luria has a proven ability to lead. In the Navy, she commanded a combat-ready unit of 400 sailors. Now, she’s stepping up to serve again,” Moulton said. “Elaine has the courage to be honest about the problems we face, put country over party, and get things done for the American people.”

Gonzales rates the race for the seat held by Republican Rep. Scott Taylor as Likely Republican.

Moulton, a retired Marine and Iraq war veteran, has spent nearly $2 million through his PAC on 19 first-time congressional candidates who have served in the armed forces. He was instrumental in providing ground support in the final weeks of Rep. Conor Lamb’s successful special election campaign in Pennsylvania’s 18th District in March.

On Tuesday, Marine veteran Amy McGrath won the Democratic nomination in Kentucky’s 6th District for the chance to take on GOP Rep. Andy Barr in a race Inside Elections with Nathan L. Gonzales rates Leans Republican.

Moulton’s team sent out 44,000 peer-to-peer text messages in the district on the final weekend before the primary urging voters to hit the ballot box.
