Williams, whose January debate tussle with Newt Gingrich was the highlight of Gingrich's presidential campaign, conducted a 16-minute interview with freshman GOP Rep. Raul Labrador on Fox News Latino.
In a post-interview commentary Williams touts Labrador's "emerging national media profile" and says his safe 1st District seat will make him a player "for many years to come."
Williams said Labrador can play a key role in improving GOP prospects with Latino voters by pressing for immigration reform, an issue that has so far damaged likely GOP presidential nominee Mitt Romney.
"Keep your eye on Rep. Labrador," wrote Williams on Wednesday, after the Tuesday interview. "He is one of the few Hispanic Republicans with the conservative credentials and the political awareness to effectively convey this new message of inclusion towards immigrants."
Williams also says Labrador's membership in the Mormon church uniquely positions him to boost his influence. The interview focused on Hispanic politics, immigration and Romney's Mormonism.
Labrador reprised a signature moment in his 2010 upset primary victory over establishment favorite Vaughn Ward, when he corrected Ward's mistaken idea that Labrador's native Puerto Rico was a foreign country, not part of the United States.
"The bottom line and what really matters is that the people of Idaho rejected that message," Labrador told Williams.
Labrador said he expects the media to "cast aspersions" on the LDS church on behalf of President Obama. "They're going to do the president's bidding," Labrador said, saying of Obama, "He's just going to let other people do that."
Jobs and the economy are the top issue for Hispanic voters, Labrador said, not immigration as Williams asserted.
"But I do agree with you that immigration is an important issue," Labrador said. "And the thing that I would tell Romney, as I would tell anybody, is that we need to start talking about being a party of inclusion. We need to start talking about how we’re the party for legal immigration, that we actually want to reform the system so people can actually come to the United States in a legal, safe way. That's what all of us want."
Williams also asked Labrador to discuss the distrust some evangelical voters have for Mormons:
"You know, I think every American is reluctant to vote for somebody who’s different than they are, whether it’s Mormon or whether something else. And I think what you have to do as a Republican, as a politician, is to convince the people that even though you're different than they are, that you still believe in the same things that they believe in. And I think everyone needs to do that. And sometimes I kind of get upset at some of my own friends who are members of the LDS faith who, who think that the only reason people are not in love with Romney is because he’s Mormon. That’s not true. He needs to enchant them just like everybody needs to enchant everybody else. I’ll give you myself an example. My state has a very large LDS population, but I'm the first LDS Congressman from my Congressional district. So, imagine -- I was LDS and I was Hispanic."
