　　Debates among candidates are rare in most countries. But they have become a staple1 of American politics, particularly during the last 25 years. Americans like debates because the candidates can be compared in an unscripted, live performance. The candidates dont know what questions will be asked, nor what their opponent might say. History indicates that a bad performance, particularly a telling gaffe2, can badly damage a candidate in the polls. The debates are a key test of the strength and abilities of the candidates, says CNN analyst Jeff Greenfield. A candidate cannot package himself in debates the way he can in party advertisements but must be quick on his feet3 to respond to unanticipated4 questions and criticisms, he adds.

　　The potential of debates to damage a vulnerable presidential hopeful is one reason why some candidates, particularly frontrunners10, are reluctant to risk their chances in such an uncontrolled environment--and the fewer debate rules there are,the less control the candidates have.But broadcast presidential debates,both in the primaries and in the general election,are now routine and expected by the American people.

　　Since 1987, the presidential debates have been organized by the bipartisan17 organization, the Commission on Presidential Debates. Its purpose is to sponsor and produce debates for the presidential and vice presidential candidates of the two major parties. In Election 2000, the commission set a threshold18 for the participation of third party candidates in the debates. They must show they have the support--as evidenced in a number of opinion polls--of at least 15 percent of the population.
