I believe that it is time for the Unions to pay taxes. They are the largest combined business in the country. They take in billions every year, and don't produce a real product. If they want to stay tax exempt they should follow the same rules as the churches. They can do their business but cannot engage in politics. If they do the may lose their status. That money is not taxed at all, the member gets a deduction and the union is exempt. If obama wants more money thats a gold mine.
