New Jersey

One study by Julia Sass Rubin, an associate dean at the Edward J. Bloustein School of Planning and Policy at Rutgers, found that being on the county line gave congressional candidates an advantage of 38 percentage points.

“We are the last of the [political] machine states, and the machine relies on the county line to stay in control,” Rubin told The Washington Post last week. “If you displease the people who decide who gets the line,” you could lose your office, she said.

“I think what [the line] produces is whatever the machine needs to produce to stay in power,” said Julia Sass Rubin, a Rutgers professor and prominent critic of the line balloting. “In Murphy’s case, because he had the resources to run and he ran as a progressive, we got a progressive governor…”

A long-simmering fight over New Jersey’s unique primary ballot design reached a federal courtroom Monday in a case that has the potential to upend not only the state’s tense U.S. Senate race but Garden State politics in general.

Rutgers University professor Julia Sass Rubin, who has analyzed the impact of the county line in elections, published a study last year that detailed the advantage it gives to candidates who have the line.

New Jersey is the only state in the nation with this type of bracketed ballot design. According to Julia Sass Rubin, a public-policy professor at Rutgers, a candidate who gets the line enjoys a double-digit advantage over the competition

This system allows parties to give preferential ballot placement to their preferred candidates, putting endorsees in a prominent location while relegating others to less visible spots known as “ballot Siberia.” That design confers an extreme advantage: Rutgers professor Julia Sass Rubin concluded that between 2002 and 2022, candidates on the county line enjoyed an average boost of 38 points.

“It’s really difficult for state legislators to have any independence. If they don’t vote the way these folks want them to, they lose the Line, and then they lose their election,” Rubin said.
Kim’s campaign, and his push against the Line, had elevated the primary race from a typical political contest to a symbolic fight over the state’s murky political ethics.
