The pattern of American presidential elections is that the more optimistic candidate, whether it's John Kennedy and let's get America moving again, Ronald Reagan, it's morning in America, or Barack Obama, yes, we can, always wins, or nearly always wins.

You want a leader, Western leader, English-speaking? Mitt Romney.

Donald Trump is writing a different theme, which is it's midnight in America and that things are bad, and they're bleak, and they're gloomy and they're doomy, and the only thing that is going to save you is someone with the authority and power of somebody like me.

The other thing that has changed - and this is more detailed to CPAC than the general Republican Party - is they have always been an outsider, Ann Coulter, sort of protest style, a little ruder than most Republicans. And this goes back all the way to [Ronald] Reagan.

The problem is that every study I'm aware of, which is probably not that many, has indicated that a dollar spent in preparation and avoidance of natural disasters is worth $15 that is spent in relief. But there's no political payoff for preparation. So, who benefits? I mean, the governor or senator or the president? Bill Clinton at Oklahoma City, his performance there helped him enormously. And there really hasn't been any regulation that would, in fact, interfere with environmental disaster.

I do think, over the last years, a lot of Republicans have decided it's not working, what the party believed in, free trade, global capitalism, open borders.

America's exceptionalism, American leadership, the American model, the American values are not [first with Donald Trump] - they're something that end at the border.
