Sweeney, the longest-serving state Senate speaker in New Jersey history, had been seen as the frontrunner to win the South Jersey seat he was first elected to in 2001.
“The Speaker of the Senate spent 20 years in Trenton,” Durr says in the clip, which begins with his exit from the cab of a truck and ends with his exit on a motorcycle. “Higher taxes, growing debt and a rising cost of living – we deserve better. New Jersey, it’s time for a change. So together, let’s end the one-party regime.
Sweeney, who has fended off better organized and heavily funded challengers in the past, has yet to concede the race.
Democrats who are already expecting a tough midterm election season in 2022 are now scrambling to craft a message to protect the party’s fragile majorities in Congress.
Asked in an interview with Fox News on Wednesday the night after the election what his priority was when he arrived at the State Capitol, Durr vowed to be a “voice for the people” but lacked details .
“I really don’t know. That’s the key factor. I don’t know what I don’t know, so I’ll learn what I need to know,” Durr said. “I’ll guarantee you one thing: I’ll be the voice, and people will hear me, because if there’s one thing people will learn about me, I have a big mouth.”
This story was updated with additional details on Friday.
