Yes, the Green candidate for president is no libertarian, and doesn't claim to be, and her economic policy is quite bad (just as is that of McCain, Obama, et al -- although at least she is less in the pocket of the corporate state). But she is great on most civil liberties and foreign policy questions, good on the prison system, good on certain corporatist trade deals, and has been one of the most principled opponents of the Iraq war, willing to vote against funding it, unlike most Democrats. Too bad she will hurt Obama on the left, but perhaps she can exert pressure on him to improve himself on these issues.
Update: I almost forgot, she also tried to get Bush impeached for crimes far worse than the ones for which Clinton was impeached in the mostly histrionic Republican crusade in the late 1990s.
