(CNN) – A poll released Wednesday showed no boost in New Jersey Gov. Chris Christie's approval rating following his keynote address at last week's Republican National Convention.
The survey from Quinnipiac University, taken August 27-September 2, indicated that 52% of adults in New Jersey approve of the job Christie is doing as governor. That's statistically unchanged from the 54% who approved of Christie in a July 17 survey. The outspoken New Jersey governor addressed delegates in Tampa last Tuesday.

The poll showed 22% of voters said Christie's speech made them think of him more favorably, compared to 18% who now view Christie less favorably and 54% whose opinions were unaltered by the speech.
"If Gov. Christopher Christie's speech marked the opening of a 2016 presidential campaign he might want to try again," Maurice Carroll, the director of the Quinnipiac University Polling Institute, wrote. "People who like the governor liked the speech; those who don't didn't. The net result – zero."
In his speech last Tuesday, Christie offered a solid endorsement of Mitt Romney's candidacy for president, though much of his remarks were focused on advocating a tough-minded approach for dealing with the nation's economic and political problems.
The New Jersey governor, well known for his plain (and sometimes unvarnished) style of speaking, stuck to his familiar style in the coveted keynote address aimed at firing up the party faithful and appealing to a prime-time television audience.
"We are demanding that our leaders stop tearing each other down, and work together to take action on the big things facing America," Christie said, adding that the nation's leaders have been crippled by the desire to be loved.
"Tonight, we choose respect over love," he said.
In a potential gubernatorial match-up with Newark Mayor Cory Booker, Christie leads 47%-40%. Among men, Christie leads Booker 55%-35%, while women go for Booker 44%-40%. Booker's favorability rating among New Jersey voters was 49%, though 38% said they haven't heard enough about the mayor to form an opinion.
The Quinnipiac University poll was conducted by telephone among 1,560 registered voters between August 27-September 2. The sampling error was plus or minus 2.5 percentage points.
