(CNN) - Another new poll from a crucial state in presidential election years indicates Gov. Chris Christie has lost support in Florida and would trail potential Democratic contender Hillary Clinton by 16 percentage points in the Sunshine State.
According to the Quinnipiac University survey, Christie has the backing of 9% of registered Republicans in the state, down from 14% in November.

Christie also got 9% in a New Hampshire survey released Wednesday. The Granite State holds the first-in-the nation presidential primary during election years.
" 'Bridgegate' is having a negative effect on his presidential fortunes in Florida," Peter Brown, assistant director of the Quinnipiac University Polling Institute, said in a news release. "Since Florida is the nation's largest swing state, and one of the early primary states, the numbers are not good news for the New Jersey governor as he tries to weather the storm from the controversy."
The poll was conducted after Christie traveled to Florida earlier this month to campaign for incumbent Gov. Rick Scott and the Republican Governors Association, which Christie chairs.
If the election were held today and Christie and Clinton were the two nominees, the Republican governor would lose by a margin of 35%-51%, according to the new poll. In a November Quinnipiac survey, Christie was only behind Clinton by four percentage points, 41%-45%.
Former Florida Gov. Jeb Bush, meanwhile, remains at the top of the potential GOP list and picked up a few points in recent months, going to 25% from 22% in November.
The race would be much tighter in a matchup between Clinton and Bush, with the former secretary of state ahead of Bush by only six percentage points, 49%-43%.
As most other polls indicate, Clinton would dominate in the Democratic primary in Florida. She comes in at 64% among registered Democrats, with Vice President Joe Biden at 9% and Sen. Elizabeth Warren at 5%. Warren has said she will not run in 2016.
Besides Bush, who tops the potential GOP primary field at 25%, Sen. Marco Rubio is another GOP favorite in Florida and comes in at 16%.
Sen. Rand Paul of Kentucky also gets in the double digits with 11%. All other potential GOP candidates fall under 10%.
Quinnipiac interviewed 1,565 registered voters in Florida, including 586 Republicans and 529 Democrats, for the survey from January 21-27. The overall sampling error is plus or minus 2.5 percentage points.
