Donald Trump has a strong lead over Ted Cruz in Iowa with about a week left before the first nomination contest on Feb. 1, according to a Fox News poll.

The poll of Iowa voters shows Trump with 34 percent among likely Republican caucus-goers, an 11-point bump from two weeks ago. Cruz is now at 23 percent, slightly down from 27 percent in the last poll.


The poll also shows that among “very” conservative voters, there’s a more even split between Cruz and Trump, who received 34 percent and 33 percent of that vote, respectively. Cruz had an 18-point advantage over Trump in the last poll conducted by Fox News.

In New Hampshire, Trump has more than twice the support of Cruz, the next closest candidate. The Fox News poll has Trump at 31 percent and Cruz at 14 percent. Marco Rubio follows with 13 percent.

The polls, conducted Jan. 18-21, were done over the phone with live interviewers. Each included 801 registered voters in the state and had margins of error of plus or minus 5 percentage points.

They follow a Fox News national poll released two days ago. That, too, showed Trump leading the field as the start of voting draws near.

Trump received 34 percent in that poll, while Cruz got 20 percent, Rubio 11 percent, and Ben Carson 8 percent.

The national poll was conducted over the same time period and via the same method, but interviewed 1,009 registered voters and had a margin of error of plus or minus 3 percentage points.
