Lower Township - A spouter says "The NJEA teachers union is backing Democrat and current union president Sean Spiller for governor. Teachers and school staff members dues ($35M) are funding his campaign." That is a lot of money out of the pockets of teachers. Are 100% of teachers and staff members democrats? Or are Republican teachers and staff members being forced to pay for a candidate they don't support? This doesn't seem like a proper use of union funds since it goes to the benefit of the union's president.
