Yes, we can.

Well, the article doesn't present any evidence of "shift." It doesn't present a single position that shows a more centrist position by Obama in the past let alone that he has moved to the left on it. It pretends confusion as to why Obama would just now be talking about such "liberal" (I fail to see how opposition to the border loosening elements of NAFTA is a liberal position but let's say it is) now when the answer is obvious (uh... two states hugely impacted by NAFTA and also in possession of a huge number of delegates are the current focus of the campaign. It is no surprise that NAFTA wasn't such an issue in Hawaii and Georgia).

He is also saying almost the exact same things about NAFTA as Clinton, so has she also taken a sudden startlingly leftward jaunt?

So, I don't actually see any reporting. Just quotes from strategists who disagree with strategy while presenting no evidence of a strategist change by Obama or a change in the tone of coverage by the press.
