Not true. NJ Dems have a great bench of people to run for stuff.
Like? I just moved to Florida 3 months ago. I lived in NJ for 20 years. Outside of a few local officials like Shvonda Sumpter or old men like Rothman or Holt, there aren't many strong candidates that could even think about challenging a sitting senator.
Not sitting senator strong, but there are some good ones. All the congressmen from the D's except Coleman and Pascrell, and they are good too, just too old, Jeff Van Drew, Sheila Oliver, Sweeney, Greenwald, etc.
