A new poll shows Newark Mayor Cory Booker with a big lead in the special U.S. Senate election to complete the term of the late Frank Lautenberg.

The Monmouth University Poll released Thursday showed Booker would get three-fifths of the votes in a Democratic primary. No others would get more than one in 10.

All four Democrats were ahead of former Bogota Mayor Steve Lonegan in the general election. Only Booker's lead was more than twice the margin of error.

"Right now, Booker and Lonegan are the only two candidates in the race with significant statewide name recognition, which contributes to their strong positions in this early poll," said Patrick Murray, director of the Monmouth University Polling Institute. "It would take a huge organizational turnout effort by any of the other candidates to overcome that advantage in the short time frame of this election."

About 60 percent did not have any opinion of Reps. Frank Pallone or Rush Holt or Assembly Speaker Sheila Oliver.

The poll of 363 likely voters was conducted Monday and Tuesday. The sampling error is plus or minus four percentage points.

Two other polls this week also showed Booker ahead.
