A new poll finds New Jersey voters think Gov. Chris Christie is doing a good job, but they're not positive about re-electing him.

In a Rutgers-Eagleton Poll released Tuesday, 47 percent of voters rate his performance an ``A'' or ``B'' _ the best marks they've given him since the poll began asking the question in February 2011.

Still, nearly one in three voters gave the Republican a ``D'' or ``F.''

Forty-four percent said they would re-elect him and 47 percent said they wouldn't _ a result within the poll's margin of error of plus or minus 3.5 percentage points.

Christie has not said whether he will seek re-election next year.

The telephone survey of 790 registered voters was conducted from Sept. 27-30.
