Newark Mayor Cory Booker is leading the pack of potential U.S. Senate candidates in 2014, according to a second poll released Wednesday.

A PowerPAC.org  poll found Booker would lead Congressman Frank Pallone (D-N.J.) and Senate President Steve Sweeney (D-3) by more than 2-to-1 in a race for Democratic U.S. Sen. Frank Lautenberg’s seat. The poll also found that Booker would win a primary battle against the incumbent senator.

Forty-eight percent of surveyed Democrats favored Booker over Lautenberg, who received 21 percent. Thirty-one percent said they were unsure of who they would support in a primary between the two.

The survey found Booker also polled favorably among both men and women voters, beating Lautenberg by more than 20 percent, according to the poll.

“The  population of New Jersey closely mirrors the rising American electorate of progressive whites, young people, women, and people of color," said Steve Phillips, chairman of PowerPAC.org. “This poll shows that the people of New Jersey clearly want Mayor Booker to become Senator Booker in 2014.”

The poll indicated Pallone, Sweeney and Congressman Rob Andrews (D-N.J.) are not well-known among the state’s Democratic electorate.

PowerPAC.org worked with Merriman River Group to survey 1,170 New Jersey registered Democrats from Jan. 7-9. The survey was conducted through automated telephone interviews and has a margin of error of +/- 2.90 percent.

PowerPAC.org bill itself as a social justice advocacy organization whose mission is to increase voter participation among underrepresented communities.

A Quinnipiac University poll released today showed Booker leading Lautenberg.
