TRENTON, N.J. (CBS) – As New Jersey Governor Chris Christie ponders a potential Republican Presidential run, a new poll in his home state shows a continued erosion of popular support.

Christie has always said he’s never put much stock in polls. So David Redlawsk, director of the Rutgers-Eagleton poll, suggests today’s numbers probably won’t make much of a difference to the Governor:

“Fifty-four-percent of New Jersey registered voters disapprove of the overall job he’s doing, while just 41-percent approve. This is the lowest job approval we’ve reported for the Governor.”

It gets worse. Less than half of those surveyed now like how he’s handled recovery from Superstorm Sandy. And his approval rate on handling taxes, the state budget, the economy and jobs are all at term lows (none better than 31-percent).

“If he’s got his sights set on the national stage, that’s where he’s focused and frankly, I think the numbers here in Jersey are partly because he’s become so focused nationally,” says Redlawsk.

But it’s not all bad for the Governor. His personal favorability numbers are a little better — at 48-38 negative — compared to 53-37 in February.
