(CNSNews.com) - Because of his "ethical problems," Newt Gingrich is not the right candidate to run against President Barack Obama in 2012, says Rep. Jason Chaffetz, a Utah Republican who has endorsed Mitt Romney.
"I do think experience matters," Chaffetz told CSPAN Thursday morning. "I have nothing personal against President Obama. He's a very nice person, he's been very nice to me, he's got a beautiful family. I disagree with his policies and his positions."
Chaffetz said one of the reasons he supports Mitt Romney is Romney's family life: "He's been married for 42 years, he got this wonderful, beautiful family, he's been scandal-free in his personal life.
"That's the kind of person -- that's what the Democrats did, right? They put up someone with a beautiful family in the Obamas. And we need to put forward someone of equal integrity."
Chaffetz said he hopes that voters in upcoming primary states will ask themselves, "Why is it that people keep going to Mitt Romney?"
There's a reason why Romney has done "exceptionally well across the country," Chaffetz said, "and I think as voters start to focus on that and start to look at that, they're going to realize Mitt Romney's the best person."
Chaffetz said he's always believed that Romney is "a very conservative person," and he also said the "electability issue" matters.
It would be foolish for the Republican Party to put a "Washington, D.C., insider" and a "K Street lobbyist" up against Obama in the fall, he added:
"I can't imagine that the middle ten percent of voters in America who are probably going to decide this election are going to look at that and say, 'Oh yeah, that's what I want, I want a lobbyist for my next president.' I don't think that's what the country's looking for. So the electability issue is certainly key for Mitt Romney."
