In a state like WI, Walker has friends in the media that would go up to the protestors and ask those kinds of questions and it's a fair question. These folks are all about Help, Hope & Change while Republicans and Libertarians are portrayed as those who sit at home clinging to their guns and religion.
Politically I've always believed that the best defense is an aggressive offense and I'd be challenging these maggots daily, making public appearances as often as possible to sap their resources. Run then out of money would be the goal. I would make sure their antics were video taped if not by the media then by a private firm that i would use campaign funds to pay for if need be. I would publish the video's, making them available to any media outlet free of charge. Even though it's a few years before re-election I'd get some video of the protest at the Special Olympics event and put together a commercial that asks the tough questions and I'd start running them. I would make them outrageous enough that the National Media would run them as news and make myself available to Fox, MSNBC, CNN and the like. I'd be on them like stink on manure all day everyday calling them out at every opportunity.
There is one sure fire way to defeat the Progressives and that is to expose their morally and financially bankrupt viewpoint for all to see and that's how you beat them. Chris Christie does a splendid job of facing the fire. Walker is a nit wit with paper balls instead of the solid Brass Ones Chris Christie has.
