(CNN) - Two new polls in New Jersey and one in Iowa may spell trouble for Chris Christie.
One of the surveys in the Garden State puts the Republican governor's trustworthiness level at an all-time low, while the other poll indicates Christie's approval ratings are underwater.
And the survey in Iowa indicates that a plurality of Republican voters say they disapprove of the New Jersey governor's handling the George Washington Bridge controversy, which made national headlines earlier this year. Since Iowa's caucuses kick off the presidential caucus and primary calendar, the numbers, if they hold up, are not great news for Christie, who's seriously considering a bid for the White House in 2016.
Christie's administration is facing both federal and state investigations over allegations that some of his aides closed access lanes to the nation's busiest bridge last September to punish the mayor of Fort Lee, New Jersey, for not endorsing Christie's re-election. The governor has denied knowing anything about the gridlock until after it occurred and has said he knew nothing about any political mischief by members of his administration. But the controversy has put a cloud over Christie's political future.
According to a new Fairleigh Dickinson University's PublicMind survey, Christie's approval rating stands at 41% among New Jersey registered voters, down from 48% in January and 61% in November, soon after his landslide re-election as governor. Forty-four percent say they disapprove of the job Christie's doing in Trenton. This appears to be the first time that Christie's approval rating as governor is lower than his disapproval rating in New Jersey polling.
"Unfortunately for the governor, the investigation appears to be turning him into a more polarizing figure," said Krista Jenkins, executive director of Public Mind.
The poll's early Tuesday release came as a separate survey, from Rutgers-Eagleton, indicated that just 23% of Garden State voters say the term "trustworthy" applies to Christie. That's an all-time low in Rutgers-Eagleton polling. Another 38% say "trustworthy" somewhat describes Christie, with 35% saying the term doesn't apply to the governor at all.
The director of the Rutgers-Eagleton poll says that the bridge controversy's taking a toll on the governor's personality traits.
"Trustworthy was one of Christie's hallmarks, especially given voters' normal cynicism about politicians. Losing the trust of voters puts Christie into the category of an ordinary politician," said David Redlawsk.
Meanwhile, a new poll from the Des Moines Register indicates that 47% of Iowa Republicans disapprove of how Christie's been dealing with the bridge controversy, with 34% giving him a thumbs up.
The Des Moines Register poll was conducted Feb. 23-26, with 703 Iowans questioned by telephone. The survey's overall sampling error is plus or minus 3.7 percentage points.
The Fairleigh Dickinson University poll was conducted March 4-9, with 703 registered voters in New Jersey questioned by telephone. The survey's overall sampling error is plus or minus 3.7 percentage points.
The Rutgers-Eagleton Poll was conducted Feb. 22-28, with 729 Garden State registered voters questioned by telephone. The survey's sampling error for registered voters is plus or minus 3.6 percentage points.
