Biden takes a risk

He's a lifelong Democrat whose entire career has been spent litigating environmental issues and minority rights, who Obama considered appointing to head the EPA, and who has repeatedly spoken out against corporatism. If you don't like some of the unscientific things he's said then I definitely don't blame you, but "Republican" is not a synonym for "I don't like him."

She's a hippie who bounced around a bit in life until she found success as a New Age guru. (That's not a criticism, I bounced around a bit in life too!) Her platform is the furthest to the left, but not passing the edge of the mainstream. Her detractors paint her as a lunatic, which she isn't. When they mention her at all, the media tends to just report on what a longshot she is rather than on her actual positions, which does both her and voters a disservice.
