New Economic Perspectives has the article Is Progressivism in the Eye of the Beholder? by Joe Firestone. He is critiquing a post by Thomas Palley. He quotes Palley as follows:

In Clintonworld, it seems that playing a central role in catastrophic policy failure or peddling bad economics doesn’t disqualify you from future influence. If anything, a record of being disastrously wrong on economic policy seems to be a required credential.

This is something that even I forget when Clinton tries to put on the charm to pretend that she gets the idea of what being a progressive is. Joe Firestone gives a good account of what would be necessary for us to believe Clinton has really reformed. However, he comes to the following conclusion:

Perhaps Sanders is that authentic candidate. But Hillary Clinton, I’m afraid, can never play that role!
