As Gov. Christie pitches himself nationally as a straight-talking leader, fewer New Jersey voters than in the past are associating him with certain positive traits, according to a Rutgers-Eagleton poll released Tuesday.

Asked how well trustworthy described the Republican governor, for instance, 17 percent of the state's voters said "very well" - a decline from 22 percent in October and 27 percent in January 2014, after the scandal over the George Washington Bridge lane closures broke.

Before Christie's November 2013 reelection, 43 percent of New Jersey voters surveyed by the poll said trustworthy described him "very well."

The poll released Tuesday found 36 percent of voters said Christie, who is considering a run for president in 2016, was "somewhat" trustworthy, and 44 percent said "not at all."

Among Republicans, 37 percent said trustworthy described Christie "very well," down 11 points in six months, according to the poll.

On strong leader, 39 percent said the term described Christie "very well," down from 47 percent in October and 54 percent in March 2014.

The new poll also found 26 percent of voters said effective described Christie "very well," compared with 31 percent in October and 44 percent in January 2014.

The poll of 860 New Jersey adults, including 722 registered voters, was conducted March 27 to April 3. The margin of error for the registered voters is 4 percentage points.

Another poll, released Monday, found more than half of the state's voters disapprove of the Republican governor's job performance - an all-time low for Christie in the poll.

According to the Quinnipiac University poll, 56 percent of the state's voters disapprove of Christie's job performance, while 38 percent approve. In Quinnipiac polls between August 2014 and January, Christie's rating ranged from 46 percent to 49 percent approval, with less than 50 percent disapproval.

Nearly two-thirds of New Jersey voters surveyed by the poll released Monday also say Christie would not make a good president, compared with 29 percent who said he would.

New Jersey, where 58 percent of voters chose President Obama in 2012, has gone for Democratic presidents in every election since 1992.

Among registered Republican voters in New Jersey, the largest share - 22 percent - favored Christie for president. Next was Wisconsin Gov. Scott Walker, favored by 14 percent, followed by former Florida Gov. Jeb Bush at 11 percent. Thirteen percent said they didn't know.

On whether they would like to see Christie run for president, 56 percent of New Jersey Republicans said they would, while 41 percent said they would not.

In a general election contest, Democratic presidential candidate Hillary Rodham Clinton led by Christie 51 percent to 36 percent in New Jersey, the poll found.

On personality traits, the poll found that 63 percent of voters, asked whether Christie had strong leadership qualities, said yes. Thirty-three percent said no.

The question was posed differently from the Rutgers-Eagleton poll, which asked voters to choose between "very well," "somewhat," and "not at all."

The Quinnipiac poll also found that a majority of New Jersey voters - 53 percent - believe Christie knew aides were causing the September 2013 traffic jam at the George Washington Bridge.

Christie has said that he had no involvement in the closing of access lanes at the bridge and did not have advance knowledge of a plot to snarl traffic. A federal investigation into the incident and related issues is ongoing.

If Christie were proved to have ordered the lane closures or known what aides were doing, 34 percent of New Jersey voters said, he should be removed from office, while 29 percent said he should be removed and prosecuted, according to the poll. Another 29 percent of voters said an apology would be sufficient.

The poll of 1,428 New Jersey voters, conducted April 9 to 14, has a margin of error of 2.6 percentage points. Among the 444 Republicans surveyed, the margin of error is 4.7 percentage points.
