Here's a quote from Nader from the Oct 18 issue of The Nation about what he calls "the most amazing unconditional surrender by the left in decades":

"They (the left, especially those who supported his candidacy in 2000) made no demands. They forgot the wisdom of Frederick Douglass, who taught us that power concedes nothing without a demand. If the left does not exert pressure on Kerry, the only pull he is going to feel will be from corporate interests. If the left does not make Kerry better, he gets worse. He moves to the right. And when Kerry moves to the right, his poll numbers go down. So, you see, when liberals back Kerry without asking anything of him, they don't do him any favors. That's why he's losing what should have been an easy race."
