I'd say that people are pretty animated. And besides, the real issue confronting Democrats at the national level is 'voter suppression' and 'gerrymandering'.
No, Mets, this isn't an invitation for you to come in and start ranting about 'geographic sorting' again (which is a nonsense way to talk about the urban/rural divide and the fact that people tend to congregate in dense population centers.).
As for Sanders, he'll have to say 'I'm a Democrat' and actually walk the walk and have a 'D" after his name. That shouldn't be a problem for the guy. /If he wins/, he'll have all the leverage he needs to force changes that he approves of. Of course, given his track record with nominees and personal lack of transparency, that may not be such a good thing, no matter how much I agree with things he's said.
