Not at all, and I don't love hearing what anti-progressives have to say so I'm not going to wade through that google search. I'm just saying that one reason those cities have a higher turnout for Democrats is because a lot of them are (or were) in labor unions.
Are you saying that those union members wouldn't self-identify as progressive? Or that progressivism has moved beyond endorsing labor unions? Or something else?
> Are you saying that those union members wouldn't self-identify as progressive?
Lots of union members self-identify as conservative, and have policy preferences consistent with that on most issues other than labor issues; in many cases they are Democrats, but not progressives.
Certainly there must be polls out there with this information, but apparently I can't quite suss out the search terms to find it. What area's do you think these union members are conservative on? Free trade? Minimum wage? Corporate tax rates? I suppose those might be on the labor side of things. Abortion? Military spending? Public school spending? Universal health care? Social Security privatization? Legalizing marijuana?
