A new poll released Tuesday reveals that Newt Gingrich has widened his lead in Iowa.
The ABC News/Washington Post poll finds Gingrich ahead the rest of the field in pursuit of the Republican presidential nomination.
Thirty-three percent of likely caucus voters prefer Gingrich.
Mitt Romney and Ron Paul are tied for second at 18 percent.
Rick Perry scored 11 percent support in the poll, followed by Michele Bachmann at 8 percent; Rick Santorum, 7 percent; and Jon Huntsman, 2 percent.
The polling also revealed that Iowa Republicans may still have not settled on a candidate. Fifty-two percent of respondents say there's a chance they may yet change their minds before the Jan. 3 event.
Langer Research Associates produced the poll for ABC News. It was conducted by landline and cell phone Nov. 30-Dec. 4, among a random sample of 858 potential and 356 likely Iowa Republican caucus-goers.
The results have a margin of sampling error of plus or minus 4 points for potential caucus voters and 6 points for likely participants.
