I just watched the interview. I don't think she will get her viral moment from it. She comes across as nice and reasonable, but she hadn't got the sort of simple message that wins an election. Saying you are a centrist, or appearing to be, like AK, isn't very interesting or stimulating.
She also avoided answering the question I was interested in about identity politics and the Democratic party, because that is an issue for many voters. If you are a supporter, there is an argument to make. If you are not, then say it: people respect an opinion.
By the way, I am not sure that simplified messages are wise. But they are effective. Everyone knows that Elizabeth Warren has "a plan for that". She has a clear vision of a different America. More Scandinavian, as I see it. It isn't socialist. But it has more social elements to it, a larger role for the common good, more regulations for Wall Street, less inequality etc. For myself, I think it assumes that business can thrive in the environment she proposes and I am not convinced. But I respect her character and her attention to detail and her clarity. And I think the USA could bear a few more Scandinavian features in its politics. Those countries seem to thrive in ways that the US might envy if it ever looks in that direction.
