So not surprising to me that she describes Trump supporters' concerns about immigration and, even more predictably, "unfair trade deals" as rational. On trade more than immigration, there is a clear intersection between those feeling the Bern and those lining up behind Trump. I think it goes further than that - both sets of supporters see themselves in an insurgency against the mainstream - the establishment.

I think this could be the story that ultimately explains a Trump victory in November. All those Bern voters in Indiana - who will they be voting for in November if the Bern doesn't pull off the miracle comeback? In Trump's recent 1st 100 days interview with the NYT, one of his first acts, he claims, will be to call all the most powerful people in American business and "threaten punitive measures if they move jobs out of the US". I find that chilling - the key here should be making ourselves more competitive, starting with corporate tax rates. Not taking a page out of the Chinese dictatorship's book, hauling a bunch of trembling executives before the king's chair like an episode of "The Apprentice", and holding a gun to their heads.

But Bern fans? I suspect they love that kind of talk. So who will they be voting for in November?
