New Jersey voters remain split on Gov. Chris Christie, but they're pretty sure he's preparing to run for president in 2016.

A Rutgers-Eagleton poll out Tuesday found Christie's job approval continues to hover just above 50 percent.

Fifty-two percent of registered New Jersey voters said they approve of the job he's doing, down slightly from April.

Christie fares worse on issues. Fewer than 50 percent approve of the way he's handling taxes, the state budget and pension funds, but 57 percent expect Christie to run for president.

"As Gov. Christie clearly lays the groundwork for a possible presidential run, the results in New Jersey are a mixed bag," said David Redlawsk, the poll's director and professor of political science at Rutgers University. "While Christie gets a positive overall rating – one that is pretty good for a Republican in an otherwise Democratic state – concerns about specific issues are quite high and have the potential to drive down his overall support over time."

Forty-eight percent believe Christie's decisions on state issues, including whether to sign or veto bills, are more influenced by his potential candidacy than what's best for New Jersey.

The poll of 750 registered voters has a margin of error of plus or minus four percentage points.
