As I predicted here and here, Ralph Nader has confirmed that he's running for the American presidency.

He told NBC's Meet The Press he'll run as an independent.

It was quite clear from the interview I did with him last month that he'd run, despite receiving thousands of e-mails urging him not to.

It's difficult to be sure whether Nader really wants to challenge the Democrats and Republicans -- or just boost his own ego.
