Since I've given Paul Krugman lots of shit about many of his anti-Bernie columns I feel obligated to give kudos to a good anti-Bernie column. (Yes, despite the fact that he has no idea that I've been giving him shit nor would he care if he did know.)
I pretty much got his point of view from earlier columns but they were very dismissive of any point of view that would lead someone to support Sanders over Clinton, which, frankly is what is relevant. We are not looking at these two candidates vs. Platonic forms but vs. each other, and there are perfectly legitimate reasons to select either candidate depending on your personal preferences/ideas.
I also agree with Krugman's problems with Sanders, but I'm not sure I agree so much with him on Clinton. I think it is quite possible she learned the wrong lessons from Iraq and the financial crisis...not nothing as with Republicans, but still not the right lessons.
