Iowa Voters Dismiss Trump's Questions on Cruz Citizenship

— -- Donald Trump's questions about Ted Cruz's citizenship may not be helping him in Iowa. In fact, they may be boosting his rival according to one group of Hawkeye State voters.

In his latest focus group, pollster Frank Luntz asked if the fact that Cruz was born in Canada, to an American mother, raised legitimate concerns about his eligibility for president, as Trump has suggested. Only six of 27 participants raised their hands, even though seven identified Trump as their first-choice candidate.

One participant said the issue exposes Trump as "unserious,” while another called it a “joke.”

"Just a few months ago, he said his strongest lawyers said it's a settled issue and Cruz is eligible," one participant said. "Now three months later, when Cruz overtakes him in the polls, he says the exact opposite... It's not a serious issue at all."

The focus group expressed admiration for Cruz's handling of the situation, one member specifically calling his “Jump the Shark" tweet response to Trump "awesome."

"He's making a joke of this whole thing because that's what it is," one participant said.

"It's Ted Cruz. Rather than fight it and do something negative, he came back and found something positive and humorous," another added.

But some focus group members said they thought the issue could be legitimate.

"We are nation of laws. And it was important the last time around, with the current president -- if you don't qualify you don't qualify," a participant said, citing questions Trump raised about President Obama's birth, which were proven false.

"There are certain requirements to be president, and I don't care who it is, they have to prove that they are eligible to become president," another participant added.

The focus group, conducted by Luntz and Google in Des Moines, was made up of likely GOP caucusgoers with a mix of first choice candidates: eight supporting Cruz, seven for Trump, four for Marc Rubio, three for Ben Carson, two for Chris Christie, and one each for Jeb Bush, Carly Fiorina and John Kasich.

Trump did get some positive reaction to his new television ad, featuring his stances on banning Muslims from entering the U.S. and building a border wall with Mexico.

"He's spot on. The things he talked about in that ad is what's affecting America right now -- illegal immigration and ISIS," one participant said.

But when Luntz asked the focus group whether they think Trump is going to win the Iowa caucuses, only two participants raised their hands.

"Oh, he won't be happy with that. Only two of you," Luntz said.

One focus group member said that Trump supporters may not translate into actual votes on February 1 in Iowa.

"I'm not convinced his supporters are caucusgoers. You got to give three hours of your night," the member said, as other participants nodded in agreement.

Seven participants in the focus group went so far as saying that if Trump were the GOP nominee, they would not vote for him.

"I know a lot of people who say they will vote for Hillary before they'll vote for Trump. And they're Republicans who say this," one participant said.
