No doubt [Pat] Buchanan has risen in the polls in New Hampshire and elsewhere partly because he is saying what many Americans want to hear -- that American jobs are being lost to Mexico and other countries, and that the North American Free Trade Agreement, which many unions strongly opposed, contributed to this loss.

Some voters familiar with Buchanan's extremist views are concerned that many blue-collar workers who vote Democratic would vote for him over Clinton in November. That's one reason why Harvard Law professor Alan Dershowitz calls Buchanan "the most dangerous man in America."

Explains Dershowitz: "Buchanan is the man closest to power with the most extreme views. There have been men close to power with no extreme views, and there have been men with extreme views that were not close to power. But we've never had a candidate with such extremist views and so close to power."
