I don’t know about public unions,but I heard some one say recently,that unions contribute 90% to Dems.
I was just shredding all the Dem flyers from the last election that was 100% supported by my union.I was furious at the money spent.I was saving these flyers to bring to the next union meeting to show where our money goes.
I called the union not too long ago and said,I don’t want my money going to political parties.I am now a fee paying non-member with no rights,but oh,yeah I still have to pay dues.
