A recent poll from Quinnipiac University shows Newark mayor Cory Booker is preferred over incumbent N. J. senator Frank Lautenberg for U.S. Senate in 2014 by more than half of New Jersey Democrats.

Released on Wednesday, the poll shows Booker with a substantial lead over Lautenberg of 51 – 30 percent.

After making a final decision to run for the Senate, and not take on Governor Christie in 2013, Booker has gotten some push-back from Lautenberg.
