Mr. Nader, the Green Party's presidential candidate in 2000, pledged to run as an independent in March and courted endorsements of the Green Party and the Reform Party. The Reform Party endorsed him, but the Green Party instead nominated longtime activist David Cobb. Without a convention of his own, Mr. Nader views the Democratic and Republican gatherings as ways to attract much-needed attention to his campaign. During the Democratic Convention, he expects to place an opinion piece in the Boston Globe on withdrawing from Iraq and other issues that Democrats won't discuss at the convention. He will also appear on a major talk show, says Nader spokesman Kevin Zeese. "We're still hoping for 'Good Morning America,' " Mr. Nader says.
