Look for the Union Label

As I shuffled through materials from my archive of Chiles records, I noticed that even back in his state legislature years 1958-1970, he always got union-printed business cards and other materials.
I know that back in the old days, the phosphate mine unions in Polk County were strong.

I see that a number of unions --carpenters, steelworkers, etc--have endorsed John Edwards for President on the Democratic side, but their strength today is less than half what it once was.

Also in honor of Labor Day, here is an article on the influence of today's labor movement on the presidential election.
