Today at the Missouri Ethics Commission for Chris Koster’s (D) 2016 gubernatorial campaign:

C031159 07/16/2016 KOSTER FOR MISSOURI American Federation Of State County & Municipal Employees 1625 L Street NW Washington DC 20036 7/14/2016 $500,000.00

[emphasis added]

That’s enthusiastic.

They probably noticed that the republican gubernatorial field isn’t very sympathetic to organized labor.
