There's already been much attention devoted on the blogs to her response (see above video) during which she appeared to get ratty. I agree the exchange only serves to underline one of her great weaknesses - that people don't like her. But I thought her response demonstrated a more serious problem - that she doesn't really get what the clamour for change among Democrats is about. She did what she always does now in answer to the challenge that she does not represent enough change, by reeling off a list of things she has actually managed to do in Washington.

It's an impressive list - children's health insurance, support for US troops - but as important and concrete as these things are they don't seem to match up to the much bigger, almost spiritual dimension of change that I think Obama represents. The critique of Obama - fairly - is that what he says is all very inspirational but hopelessly vague and ethereal. But Hillary's problem is that this is what people seem to like. The desire for change is about more than a desire to change a few policies here and there, it is about transforming the very nature of politics and the fact is, with her baggage, Hillary just can't do that.
