I thought it was significant that Hillary's message in her victory speech upon her comeback surge was decidely anti-corporate power, making the issue not just about "change" but about where the problem is coming from:

The oil companies, the drug companies, the health insurance companies, the predatory student loan companies have had seven years of a president who stands up for them. It’s time we had a president who stands up for all of you.

The reality is that when Democrats win when they actually appeal to working class voters. They are usually too enmeshed in the web of their corporate donors and consultants to make this winning appeal, but when they get desperate-- as Hillary now is -- they actually deliver that winning message.

It will be interesting to see how Obama responds if he ends up with Hillary and Edwards to his left on an anti-corporate power message?
