In New Jersey's 9th Congressional District, a longtime Democratic stronghold with a D+12 partisan lean, trader consensus favors the Democratic Party at 78% implied probability, driven by nominee Shavonda Sumter's commanding lead over Republican Billy Prempeh. Rep. Bill Pascrell's death on October 21 prompted a swift Democratic nomination of Sumter, a veteran assemblywoman with strong local endorsements from Gov. Phil Murphy and Sen. Cory Booker. A late October Data for Progress poll shows Sumter ahead 55%-23%, aligning with the district's history of lopsided Democratic wins—Pascrell took 70% in 2022. Absent major shifts before the November 5 election, markets reflect low upset risk amid undecided voters.
