Booker has strongly hinted that he plans to seek the seat of retiring Sen. Frank Lautenberg (D-N.J.). The 89-year old is the oldest member of the Senate, and he announced last month he was retiring. Polls at the time showed him significantly trailing Booker in a potential primary challenge.
In a poll released earlier this week by Fairleigh Dickinson University, half of Democratic primary voters said they hoped Booker emerged as their party's nominee. Neither Rep. Frank Pallone (D-N.J.) nor Rep. Rush Holt (D-N.J.), both of whom have expressed interest in a run, cracked double digits.
