I mean, this is a fascinating moment:

Ezra Klein
You said being a democratic socialist means a more international view. I think if you take global poverty that seriously, it leads you to conclusions that in the US are considered out of political bounds. Things like sharply raising the level of immigration we permit, even up to a level of open borders. About sharply increasing …
Bernie Sanders
Open borders? No, that’s a Koch brothers proposal.
Ezra Klein
Really?
Bernie Sanders
Of course. That’s a right-wing proposal, which says essentially there is no United States. …

You know, recently Kevin Williamson over at National Review wrote “Bernie’s Strange Brew of Nationalism and Socialism.”  And oh, but did people scream over that! …So I don’t know how they’re going to reconcile that the screaming with the sudden realization that good Old Bernie Sanders wants all those Mexicans to go back to their homes so that good, clean, American workers can take them jobs. Now, to be fair: I don’t think that Bernie Sanders is a racist. But he’s very possibly the most likely candidate in this race to start talking about Blood and Soil.

PS: Look, I know that there are people reading this who will be considerably more hard-line than I am about immigration. And that’s fine… because most of those people are also still generally small-government, which means that there’s a natural check there on the implications of their opinions.  But when a self-avowed socialist starts ranting about open borders and the evil, evil Koch brothers I will absolutely insist on retaining the right to bring up unpleasant historical parallels.
