Ensign, like Sanford a social conservative who promoted family and religious values and criticized President Bill Clinton for his Alter Egoaffair with a White House intern, admitted two weeks ago to an extramarital affair with a former campaign aide. Barbour declined to discuss SanfordAquaRacer directly. "I just don't talk about people's personal problems.

I don't think it's appropriate, I don't think it's polite, and I don't think it achieves any purpose," he said. Barbour said he doesn't think the scandal will affect a single vote in this fall's gubernatorial races in NewCarrera Jersey and Virginia.

 "For us as Republicans, the biggest classic exclusiveissue about this or about spending or about other policy issues is Republicans need to do what they say they're going to do," said Barbour, who took over leadership of the Republican Governors Association when Sanford resigned from that post.

 "I mean, that's the issue. Are you going to do what you say you're going to do?" Romney agreed that everyone makes mistakesFormula One but asserted that people in public life ought to be held to a higher standard.

"Not all mistakes are the same. And notkirium everybody is a governor or a senator or a president. And we expect people to live by a higher standard because what they do is going to be magnified. Their families are going to be hurt more by what they do," Romney said.

"The things they care about will be hurt. And the culture of the nation and the people who follow them will be hurt." Some Republicans won't live up to the party'sLink values and its standards of ethical conduct, Romney said. "That's going to be true," he said. "But not speaking about things that are important would be an enormous mistake."

 Romney said a second presidential run is "wayMonaco beyond my horizon at this point" and that he is focusing on helping Republicans running for office this fall and in 2010. As for his own presidential ambitions, Barbour said: "I'd be very surprised if I ended up running for president, but I can't just say flatly no. But I would be very surprised.

My wife would be even more surprised." Asked if he was running for president, PawlentyMonza said: "I don't know what the future holds for me, but I do know this. I feel strongly about the values and principles for the Republican Party.

I believe I have something to say about that." Pawlenty spoke Sunday on CNN's "State other Watchof the Union" while Barbour appeared on CBS television's "Face the Nation" and Romney on NBC's "Meet the Press."
