Sen. Bob Menendez, D-N.J., has a slim, 2-point advantage over his Republican challenger Bob Hugin in a new poll released Monday, well within the poll's margin of error.

The Democratic incumbent leads Hugin 45 percent to 43 percent, a Stockton University poll showed.

Menendez has a 54 percent unfavorable rating in the wake of corruption charges that were dismissed following a mistrial, while just 21 percent of likely voters have a negative view of Hugin.

The Justice Department dropped its bribery case against Menendez in January after he was accused of accepting gifts from a wealthy donor in exchange for official favors.

A separate poll conducted by Quinnipiac University in August showed Menendez’s lead shrinking. Menendez led by 6 points in that poll, down from a 17-point advantage in a March poll.

The Stockton University poll, conducted Sept. 19-27, surveyed 531 likely voters in New Jersey. It has a margin of error of plus or minus 4.25 percentage points.
