(CNN) – Newt Gingrich leads the pack of GOP presidential candidates in a fourth straight poll of likely Iowa Republican caucus goers.
Thirty-one percent of people questioned in a CBS News/New York Times survey say that the former House speaker is their choice for their party's nominee, with 17 percent supporting former Massachusetts Gov. Mitt Romney and 16% backing Rep. Ron Paul of Texas. The poll's Tuesday afternoon release comes four weeks before the Jan. 3 Iowa caucuses, which kick off the Republican presidential primary and caucus calendar.
