This has nothing to do with the police, it only deals with the unions. I have googled unions supporting politicians and from what I have found summarizing several sites, 95% of the money paid to the politicians are paid to the Democrats. 80% of the workers want to decide who their dues are paid to. I remember from my working as a union member that at election time, we were given a sheet with the names of who the union was supporting and who we were to vote for. We never had a choice 30 years ago.
