Responding to the growing grassroots swell of support from ... uh ... well, we're not sure, really, consumer advocate Ralph Nader announced over the weekend that he will be running for president in 2004. This time he'll make his bid as an independent, not as a Green Party candidate as he did in 2000. His announcement was filled with sharp warnings about corporate power run amok and the two-party duopoly. Of the many folks who responded with horror to the news, fearing a repeat of Nader's alleged spoiler role in the 2000 election, none were more upset than mainstream environmentalists, who say they have learned the hard way over the past three years that Tweedledum is actually quite a bit more hostile to the environment than Tweedledee. Muckraker surveys the reactions -- only on the Grist Magazine website.
