(CNN) – While his national poll numbers have dipped, Newt Gingrich still leads the pack of Republican presidential candidates in South Carolina.
The Clemson University Palmetto Poll released Monday showed the former House speaker with a 17-point lead over former Massachusetts Gov. Mitt Romney, 38% to 21%. Rep. Ron Paul of Texas received 10% followed by Texas Gov. Rick Perry and Rep. Michele Bachmann of Minnesota tied with 5%. The other candidates garnered less than 5%.
Monday's findings mirror those taken in the first-in-the-South primary state earlier in the month. Gingrich led by double digits in CNN/TIME/ORC, NBC/Marist and Winthrop University surveys. The most recent national poll from CNN, also released Monday, indicated Gingrich tied with Romney, a change from his top position in last month's poll.
However, the new figures indicated only one-third or 32% of respondents have decided who to support in the Jan. 21 contest. Among those who said their minds were made up, Gingrich saw a 28% jump since the November poll, while Romney stayed roughly the same and Paul moved up 6 percentage points.
The Palmetto Poll surveyed 600 South Carolina voters between Dec. 6 and Dec. 19 with a sampling error of plus or minus 4.5 percentage points.
