This morning, on Meet the Press, Ralph Nader announced yet another run for president, promising "to stem corporate crime and Pentagon waste and promote labor rights," according to AP's account. One has to wonder precisely what he thinks he will accomplish, given the deep anger many Democrats feel over his sipohoning of votes away from Al Gore. But perhaps he is addicted to the campaign trail. Or he might wish to help Barack Obama look more like a centrist. Or maybe he really does feel that Barack Obama is not sufficiently punitive toward corporations.

In any event, welcome back to Ralph Nader.

[Full disclosure: I spent a year as one of Nader's Raiders, 1971-72. I haven't spoken to Ralph since.]
