“He’s a union member, and this is WI and was just after Act 10.”
You are more than a bit confused and guessing about facts not in evidence. Postal employees are not required to join one of the postal unions and the article doesn’t say whether he did. Act 10 is a Wisconsin state law. Postal workers are US government employees and Act 10 didn’t affect them.
Dude, I’m confused?????? Guessing? I lived through Act 10, you got what, a story every week or so? You don’t know how nuts these people were and are. The FACT that he only tossed out the Republican literature and delivered the Dim lit is all I need to know about his motivations.
