(CNN) – Sarah Palin's support among likely Republican primary voters is fading according to a newly-released Gallup poll, the second national survey this week to indicate the Alaska Republican is headed in the wrong direction as the 2012 primary race gears up.
According to the Gallup survey, which was released Friday, Palin draws 12 percent of support from Republicans and Republican-leaning independents - a 4 percent decline from a similar Gallup survey conducted one month ago. Those results are similar to a CNN/Opinion Research Corp. poll released earlier this week showing Palin had fallen 7 points between January and March, from 19 percent to 12 percent.
Recent surveys from Pew and NBC News also indicate the former Alaska governor and 2008 GOP vice presidential nominee's current support hovers around the low double digits – a definitive drop from her showings in similar polls earlier this year.
Meanwhile, the new Gallup poll indicates former Arkansas Gov. Mike Huckabee remains on top of the GOP presidential field with 19 percent, followed by former Massachusetts Gov. Mitt Romney, at 15 percent. Both men, who made bids for the White House in the 2008 campaign, remain within the survey's sampling error. But should Huckabee and Palin decline to run - as both have shown signs they may - the poll shows Romney's support surges to 22 percent.
Behind Palin, former House Speaker Newt Gingrich is at 10 percent, Rep. Ron Paul of Texas, another GOP presidential hopeful from the last election, comes in at 6 percent, and Rep. Michele Bachmann of Minnesota – who CNN reported Thursday is set to form an exploratory committee in June or earlier – garners 5 percent.
A string of other potential candidates are in low single digits, including Indiana Gov. Mitch Daniels, former Minnesota Gov. Tim Pawlenty, Mississippi Gov. Haley Barbour, former U.S. Ambassador to China Jon Huntsman, former Sen. Rick Santorum of Pennsylvania, and former New Mexico Gov. Gary Johnson.
Businessman Donald Trump scored 1 percent in the poll, though his name was not included among those who were listed to survey respondents, meaning his support came from people who actively named him instead of any on the list provided by Gallup. In the CNN poll earlier this week that did include Trump's name, the "Apprentice" host and real estate tycoon stood at 10 percent.
The Gallup poll surveyed 1,082 Republicans and Republican-leaning independents by telephone between March 18-22 and caries a sampling error of plus or minus 4 percentage points.
