One poll that came out Sunday morning and straddled the Thursday night CNN debate in Jacksonville, showed Romney at 42%, Gingrich at 27%, Santorum at 16% and Paul at 11%.
If Santorum were to leave the race, the NBC News/Marist poll showed Romney and Gingrich splitting his support, with Romney's backing rising to 49% and Gingrich's to 33%.
According to the poll results from after the CNN debate, Santorum got a 5% boost while Romney lost three percentage points and Gingrich dropped four points. Paul's support didn't change following the debate.
Romney also led in a Tampa Bay Times/Miami Herald/Bay News 9 survey of likely GOP voters conducted Jan. 24 through Jan. 26 – before the CNN debate – and released Saturday evening. Romney received 42% to 31% for Gingrich, 14% for Santorum and 6% for Paul.
And an American Research Group survey, taken entirely after the latest televised debate, showed Romney in the top spot with 43% support from likely GOP primary voters, followed by Gingrich with 32%, Santorum with 11% and Paul with 8%.
A last-minute surge would have less of an impact in Florida, which allows early voting and absentee ballots for the primary, than in some other states. So far, more than 400,000 votes have been cast, according to the Florida Department of State.
The NBC survey of 3,141 likely Republican primary voters was conducted between Jan. 25 and Jan. 27, and has a sampling error of plus or minus four percentage points. The Tampa Bay Times/Miami Herald/Bay News 9 poll of 800 people has a sampling error is plus or minus 4.5 percentage points. The ARG survey of 600 likely GOP voters was conducted between Jan. 27 and Jan. 28 with a sampling error of plus or minus 4 percentage points.
