Despite his poor performance in the Republican primaries thus far, Ron Paul spoke to Piers Morgan with characteristic optimism and enthusiasm. Arguably more self-assured than Rick Santorum who appeared on the show two weeks ago, Ron Paul refuted claims that he can't win the nomination, telling Piers Morgan: "I have steady growth -- once you become a Ron Paul supporter you remain a Ron Paul supporter."

In his interview with Rick Santorum, Morgan referred to Ron Paul as "barking". While the Texas Congressman has been criticised for his slightly eccentric views, the one thing he cannot be accused of is flip-flopping, unlike fellow candidate Mitt Romney.

Despite being the oldest candidate in the field at 76, Paul has a significant youth following. "My principles of liberty are inviting to young people," he told Morgan. "Their minds are more open; they won't just accept the status quo."

Morgan went on the attack about health care, telling the Congressman that his view -- that if you can't afford health insurance you should essentially fend for yourself -- is uncompassionate. In his defence, Paul argued that the Soviet system wasn't actually able to medically care for its people because it ended up totally bankrupt. In this respect, for Paul, the worst thing possible would be to depend on the government. Speaking as a child of the Great Depression, he said: "You have to assume responsibility for yourself."

However, he failed to mention quite how people should afford backbreaking insurance prices without government assistance. So, what would vulnerable people have to do in Ron Paul's society to get healthcare? The Congressman dodged the question with the sweeping generalisation that "to produce the best middle class you have to do it through freedom, not through redistribution of wealth."

Morgan asked Paul what he thought about Romney's comment that he "isn't concerned about the very poor" -- a statement that has been taken wildly out of context. Refusing to take the talk show host's bait and go on the attack, which is undoubtedly what Newt Gingrich would have done, Paul said: "I don't have many agreements with Mitt on policy - not on foreign policy, spending policy, bailout policy - but I've ended up defending him on this." Unlike the other Republican candidates, Paul doesn't play dirty politics.

Paul did, however, sum up his political ideology: "Sound currency, limited government, contract rights, don't bail out anyone -- that's when the poor get benefits and jobs will come. I'm as concerned about the poor as much as anyone else, but I don't think robbing from one group works."

On foreign policy, Paul is a stark contrast to the views Rick Santorum expressed on the show a few weeks ago. He categorically denies that he is pacifist, but says he only believes in war when it's justified. "From a strict constitutional viewpoint I don't want to fight any wars that aren't declared and, since World War II, nothing has been justifiable because we haven't gone through the proper process." Paul said that he did not support US forces in Afghanistan following the 9/11 attacks because "the country didn't attack us -- a bunch of thugs did."

His foreign policy views stand in particular contrast to the other Republican candidates' with regard to Iran. Santorum, speaking to Morgan a number of weeks ago, said that he would have no qualms about bombing Iran. However, Ron Paul said that a pre-emptive strike would be aggression and "aggression is for dictators." His view on the pre-emptive issue has caused him to appear weak on national security. He said: "Iran is the same principle as Iraq. We were wrong to go in there and we lost 8,500 US lives."

He confirmed his isolationist philosophy by saying that the British should be the ones to "take care of Israel," not America. "Why is it assumed that we are the policemen of the world, that it's our moral obligation? Besides, we're broke!"

Paul's non-interventionist policies are certainly seen as radical and, in many ways, deeply un-Republican. Fellow GOP candidate Newt Gingrich said that Paul's views "are totally out of the mainstream," although this is a little rich coming from the man who is planning a moon colony.

Morgan bizarrely asked the Congressman whether he was "a spanker" with his children. Comparing his parenting and foreign policy views, Paul told him: "I reject the use of force and intimidation with children, as I do with politics."

The interview made for uncomfortable viewing as Morgan rarely let Paul finish a sentence. While his rigidity and firmness in his policy ideas has been praised, Paul did demonstrate a willingness and ability to modify his opinions and bend where necessary. However, the self-proclaimed "conservative liberal" is perhaps the man you want as your grandfather, not your president.
