Despite a report clearing Gov. Chris Christie of any wrongdoing in connection with the September lane closures in Fort Lee, the Bridgegate debacle may still be affecting how New Jersey voters view Christie's job performance.

In a just-released Quinnipiac University poll, 49 percent of voters approve of the job Christie is doing; 44 percent disapprove. His score was 55 to 38 in a January survey.

Meanwhile, the governor earned his worst "bully score" in the poll's history. Voters were divided, 48 to 48 percent, on whether Christie is more of a leader or more of a bully.

Of the voters who know something about Bridgegate, more than half said the investigation commissioned by the governor and clearing Christie of involvement was a "whitewash."

"They don't think it was a real investigation," said Maurice Carroll, assistant director of the Quinnipiac University Poll. "They think it was designed to clear Christie."

Voters were evenly split, meanwhile, on the legislative investigation run by Democrats in the state legislature. Forty-six percent said the investigation is legit, and the same amount called it a "political witch hunt."

The survey also touched on Christie's possible run for President of the United States in 2016. Christie would not make a good president, according to 57 percent of Jersey respondents, including a large chunk of independent voters. More than half of respondents said they would not like to see Christie run for the White House.
