Julia Sass Rubin

“It’s just a hiccup,” Dr. Rubin said. “If this decision holds, it will completely upend New Jersey politics.”

It’s called the “county line” — and it’s been the stuff of backroom Jersey politics that allowed party bosses to play an outsized role for decades in determining the winners and losers on election day. Now, a federal judge may have changed all of that with a 49-page ruling Friday that sent shockwaves through the state and could forever curb the power of those bosses.

“Democracy is about voters deciding,” says Julia Sass Rubin, a Rutgers professor and an expert witness in the federal suit that challenged the line. “We don’t need to be protected from democracy by four or five people who think they know better what’s good for us.”

A lawyer representing county clerks in New Jersey has requested that a judge delay his landmark decision of scrapping the state’s county-line ballot design, a system that critics say has given tremendous weight to establishment candidates at the expense of outsiders.

In his March 29 opinion, Judge Quraishi said that he assigned Rubin’s testimony “substantial weight,” based on her “demeanor, manner in which she testified, and substance of her testimony which was corroborated by other evidence presented.”

“It undermines the entire system of machine power,” Sass Rubin said. “It’s a different world. I just think you’ve taken away such a huge chunk of what they have to keep in power and really the only thing that makes us different.”
