This is a an obvious ploy to appeal to the union sector of the voting public. A non starter for the US and no doubt the Libs know this. Very  cynical. However, those right to work laws usually have a very deleterious effect on working conditions of unionized workers. In Wisconsin for example, the teaching profession I gather is in  disarray because of these laws, with teachers leaving the field and public schools having a tough time  hiring competent ones.
