According to a NBC News-Wall Street Journal-Marist survey released on Sunday, the Texas senator takes 28 percent support in Iowa, edging Trump, who sits at 24 percent support. That’s within the poll’s 4.8 percentage point margin of error, and in line with other recent polls.

According to the RealClearPolitics average, Cruz leads Trump in the Hawkeye State by only 2.5 points.

However, when the poll considers all potential Republican caucus-goers, and not just likely caucus-goers, Trump pulls ahead of Cruz, 26 to 24. Trump is relying heavily on the support of voters who have not participated in the political process in the past, leading many analysts to predict that he’ll underperform on voting day.

Still, many analysts are predicting record turnout at the GOP caucuses on Feb. 1, which could benefit Trump.
