the EU is so popular in Poland then though....
Yes/no polls tend to lose the nuances. As I've written before, a large majority of Polish people are in favor of membership but for mostly instrumental reasons
-ability to work abroad for better money
-economic development aid (not called that, but... that's what it is)
-some check on local government excesses (note the high number of post-communist countries toward the top)
There is, however, no... sentimental feeling (of the type that many Germans seem to have toward the EU) and there's no desire to subvert Polish identity to a larger European identity (I remember being told by someone who had lived in Germany that none of the younger people he knew wanted to be German - they wanted to be 'Europeans' first and foremost).
The real lead here however is France - more negative toward the EU than Greece! More negative toward the EU than the UK (which voted to leave....)
What's up there? The Center is not holding....
