(CNN) - Most New Jersey voters in a new poll want Republican Gov. Chris Christie to serve a second term. But only about half think he should make a White House run and they're split on whether he'd make a good president.
The release on Tuesday of the Quinnipiac University survey comes one week before the gubernatorial election in the Garden State, a contest that Christie is expected to easily win.
And it comes as the possible 2016 GOP presidential hopeful, in a new TV interview, once again declined to commit to serving a full second term if re-elected on November 5.
By a 48%-41% margin, likely voters overall in New Jersey say they'd like to see Christie run for the White House in 2016. That compares with more than seven in 10 state Republicans who would favor such a candidacy. Independents feel the same way by a 50%-36% margin.
The poll indicates voters are divided 42%-43% on whether Christie would make a good president. More than seven in 10 Republicans say Christie would make a good president, but Independents are split.
"He's near the top in all the national polls. But not with his Garden State neighbors," said Maurice Carroll, director of the Quinnipiac University Polling Institute.
If Christie does end up running for president and ends up winning, he would have to step down as governor with a year left in his term.
"I'm committed to being the best governor New Jersey can have for as long as I can possibly do it," Christie said Tuesday on ABC's "Good Morning America."
"My current intention is to spend four years, but we'll see what happens," added Christie. "You never know what life's gonna bring you."
According to the poll, Christie leads state Sen. Barbara Buono, the Democratic challenger, 64%-31% among likely voters.
Christie's held a commanding lead over Buono in all public opinion polls throughout this year's campaign. Christie's 2013 re-election bid, in blue state New Jersey, is increasingly seen as a testing ground or launching pad for a possible 2016 bid.
The Quinnipiac survey indicates there's no gender gap, with Christie leading Buono by a 2-to-1 margin among both men and women. Christie's grabbing 95% of the Republican vote, 72% support from Independents, and even 31% of Democrats are backing him.
"The election looks like a runaway," adds Carroll.
The poll's release comes as Christie gets ready to launch a 90-stop tour between now and next Tuesday's election.
The Quinnipiac University poll was conducted October 21-27, with 1,203 likely voters in New Jersey questioned by telephone. The survey's overall sampling error is plus or minus 2.8 percentage points.
