Republican presidential candidates Ron Paul and Newt Gingrich both said they were staying in the Republican presidential nomination race, even though they’re trailing far behind front-runner Mitt Romney.

“We’re not going to concede it to him,” Mr. Gingrich said on CBS News “Face the Nation.” He sought to portray himself as the underdog, likening himself to the Kansas Jayhawks basketball team, which completed a come-from-behind win in the NCAA college basketball semifinals Saturday night. “I’m going to take Kansas as a model,” he said.

Mr. Paul was emphatic, saying “obviously, yes,” he was going to keep campaigning. “There is no way I’m going to quit speaking out,” the Texas congressman said.

Mr. Gingrich offered a conciliatory note, saying that if Mr. Romney wins the nomination, he will do what he can to help Mr. Romney defeat President Barack Obama. “We are all committed to defeating Barack Obama,” he said.

Mr. Paul, on the other hand, lashed out at his Republican competitors, saying, “the other Republican candidates offer nothing” new on foreign policy, and “I am trying to save the Republican Party from itself.” He gave no indication he would support Mr. Romney in the general election, and played down the idea that he could be considered a vice presidential candidate. “I don’t see how that would happen,” he said. “There are too many disagreements.” Still, Mr. Paul played down the idea that he would launch a third-party candidacy if he loses the Republican nomination contest. “”I don’t have any plans for that.”
