The Quinnipiac Poll released Tuesday found that 41 percent said Christie would make a good president, while 44 percent say he would not make a good president. Forty-six percent of voters say Christie should run for president in 2016, the poll also found. Meanwhile, 47 percent say he should not run.

Christie has repeatedly been mentioned as possible presidential candidate. Observers have also speculated that the New Jersey governor's weight might play a factor in the governor deciding whether to run for president and, if he decided to run in 2016, the strength of his candidacy.

But New Jerseyans don't care about their governor's weight, according to the poll. Four percent said they are "enthusiastic" about a presidential candidate who is overweight and 64 percent said they are comfortable with an overweight candidate. Just 17 percent say they have "reservations" about a candidate who is overweight, and 4 percent said they are outright uncomfortable with the idea.

Seventy percent of New Jersey voters approve of the job Christie is doing, the poll found, while 23 percent disapprove. Christie's approval rating has trended around the 70 percent range for the last three months, according to Quinnipiac.

Those high job-approval numbers spill over into the New Jersey governor's race, where Christie holds a lead of 90 percent to 4 percent among Republicans and 69 percent to 15 percent among independents. The Quinnipiac poll found Democratic state Sen. Barbara Buono leads Christie among Democrats 53 percent to 29 percent.

Broken down by gender, Christie leads 65 percent to 21 percent among men and 55 percent to 29 percent among women.

The Quinnipiac poll also surveyed New Jerseyans on same sex marriage. The Supreme Court began hearing oral arguments on a same-sex marriage case on Tuesday. The poll found 64 percent of those surveyed support same-sex marriage legislation, while 30 percent oppose it.  Seventy-two percent support a same-sex marriage referendum on the state ballot in November, while 22 percent opposite a referendum.

While the top New Jersey Republican enjoys high approval ratings in the state, more New Jersey voters also approve of the job President Obama is doing than those who disapprove. Fifty-four percent say they approve of Obama's job performance, while 42 percent say they disapprove. In February, the poll found 57 percent approve while 40 percent disapprove.

The poll was conducted between March 19 and 24 among 1,129 registered voters in New Jersey. The poll had a margin of error of 2.9 percentage points.
