Is There a Parallel Between the European Left and the American Left?

John Avlon: What we're seeing in this country is a similar, I think, populist backlash to immigration that is at unsustainable levels. And the left seems to be getting absolutely nowhere in terms of absorbing this message productively., he says. Avlon: In Europe, you're seeing just a rational and reasonable reaction from European voters to say "We can handle a little bit of immigration" But when it translates into welcoming permanent new residents who are going to transform our communities, there's not much tolerance for that,. Avlon writes.
