Meyer also dismissed the notion that O’Mara could claim the mantle of most progressive among the candidates.

“We’ve accomplished more in less time than previous [New Castle County] administrations,’’ Meyer said. “There’s gonna be a lot of talk about who the progressive candidate is. The root word of progressive is progress, and if you ask people who’ve gone through the Hope  Center, if you ask people who’ve had a chance to experience a thousand kids coding and a number of other programs that we introduced at the county, that’s progress. And real progress for Delawareans.”

Hall-Long, a two-term lieutenant governor who was elected in 2017 after spending 15 years in the state House and Senate, did not agree to an interview.

Instead, the University of Delaware nursing professor who lives in a Middletown-area golf course community issued a statement that targeted the affluence of her opponents.

“I will welcome anyone into the race that wants to move Delaware forward and cares about the future for all Delawareans,’’ her statement said. “Voters have the choice between two millionaire self-funders and someone who has had boots on the ground and a proven track record of getting things done.

“I understand the rising cost of living and struggles Delawareans face. I’ve spent my entire life helping the people of Delaware and am committed to making our state the best place to live, work, and raise a family.”

Hall-Long has refused extended interviews about her candidacy, and has not spoken at all with WHYY News since her fledgling campaign was thrown into disarray within days of her September launch. Her candidacy kicked off with her staffers and volunteers starting to revolt and some resigning over her explanations for $207,000 in undisclosed campaign payments made since 2017 to her husband and campaign treasurer, Dana Long.

Hall-Long suspended fundraising for several weeks and later issued statements saying the checks to her husband were repayments for loans the couple had made to the campaign. She blamed the “errors and confusion’’ on the couple’s sloppy financial practices, and amended her reports to reflect that she — not her husband —had loaned $308,000 to the campaign. State law requires that all loans be disclosed on campaign finance reports.

O’Mara disclosed $750,000 he loaned to his campaign, and Meyer listed $580,000 in loans he made, when they filed their campaign finance reports for 2023 in January. Those reports showed that Meyer had $1.7 million in his campaign account — far more than both Hall-Long and O’Mara.

The winner of the primary advances to the Nov. 5 general election. Jerrold Price, a retired New York City and Rehoboth Police officer who has never run for elected office, is currently the only Republican candidate.

Delaware Democrats hold a nearly 2-1 voter registration advantage over Republicans, and hold all nine statewide elective posts.

O’Mara has ‘outsider or challenger status’ in three-candidate race

So what impact could O’Mara have on the contest?

Samuel B. Hoff, professor emeritus of political science at Delaware State University, said O’Mara is an attractive addition to the ballot and gives Delaware’s Democratic voters a solid third choice.

While many political insiders have said privately that O’Mara could hurt Meyer because the race is now two men against one woman in a contest where Hall-Long has trumpeted the fact that she would be Delaware’s second female governor, Hoff has a different view.

He thinks O’Mara will draw votes from Meyer because he’s seen as the outsider in the race. The professor said Meyer previously held that role because he’s not part of the entrenched state Democratic establishment, unlike Hall-Long, who has been in office for more than two decades and counts  endorsements from Gov. Carney, House Speaker Valerie Longhurst and a host of additional legislators. Carney is barred by state law from seeking a third term, but is mulling a run for mayor of Wilmington.

O’Mara’s “entry is most challenging or damaging, if you will, to Mr. Meyer,’’ Hoff said. O’Mara now has the “outside or challenger status and although he certainly was an insider, he’s been in an independent position for a number of years.’’

Hoff said the bottom line is that O’Mara could appeal to a wide range of voters.

At age 44, he’s the youngest in the race, which could make him the favorite of Gen Zers,, Hoff said. Meyer is 52, and Hall-Long is 60.

The professor also cited O’Mara’s leadership roles with the state and the wildlife group, saying his work in those posts show he has administrative experience and should also play well with environmentalists.
