Meanwhile, the Quinnipiac University poll shows Menendez with his highest approval rating ever in their surveys: 48 percent of voters approve of the job Menendez is doing, while just 31 percent disapprove. That is a significant improvement from last month, when 42 percent approved of Menendez's job performance, and 39 percent disapproved. Each Senate candidate is likely to have an important surrogate in the race. Menendez is likely to be bolstered by President Obama at the top of the ticket; Obama leads former Massachusetts Gov. Mitt Romney in the state by 10 points. And the Obama/Biden ticket even leads a potential Romney/Christie ticket by six percentage points. Kyrillos, meanwhile, is likely to rely on his ties to Christie, who remains popular in the state. A 55-percent majority of voters approve of the job Christie is doing in Trenton, while just 38 percent disapprove. Christie has posted a job-approval rating over 50 percent in Quinnipiac's polls since October. Christie is up for reelection in 2013. The Quinnipiac poll was conducted Feb. 21-27, surveying 1,396 registered voters. The margin of error is +/- 2.4 percentage points.
