A new Iowa State University/Gazette/KCRG poll of likely Republican caucus-goers finds Ron Paul leading the GOP field with 28%, followed by Newt Gingrich at 25%, Mitt Romney at 18%, Rick Perry at 11%, Michele Bachmann at 7% and Rick Santorum at 5%.
Key finding: The ISU pollsters found the race "remarkably fluid" with 37.8% of respondents indicating they were still trying to decide and another 34.1% only leaning towards one candidate. Only 28.1% indicated that they had definitely decided who they would support.
Caveat: The poll was conducted over a 10 day period and might not reflect the full impact of a barrage of negative ads hitting Gingrich.
