Texas Congressman Ron Paul says he's happy with his "good showing" in Iowa, where he finished third in the Republican presidential caucuses.
The Republican with a libertarian bent tells NBC's "Today" show he felt it was a sound performance, and "it's doing very well to be in the money" and getting an opportunity to go into New Hampshire.
Paul seeks to distinguish his brand of conservatism with "neo-conservatism," saying he doesn't understand why "some conservatives think that the more money you spend overseas, the more conservative you are."
Paul has been speaking sharply about reducing the American profile in the world, saying it needs to be less interventionist. He says he can be a significant factor in this year's election campaign because his candidacy has attracted many young voters.
Asked in a CNN interview about assertions by former House Speaker Newt Gingrich that his foreign policy views are isolationist and dangerous, Paul called that laughable.
Paul said he never votes for spending that the country cannot afford, opposes tax increases and opposes unwise military interventions and doesn't understand how Gingrich can call him dangerous.
The Texan said that when Gingrich was called to military service in the Vietnam era, "he chickened out on that ... so who's the danger to the country."
"So Newt Gingrich has no business talking about danger because he's putting that others in danger," Paul said. He said some people call Gingrich's brand of politics "chicken-hawk."
