I don’t live anywhere near Wisconsin but I can’t believe this kind if thuggery by unionists - at a State Fair - could possibly be appreciated by the majority of Wisconsin residents. It should have a huge backlash on the recall election vote (against the challengers). Pampered state employees (union members) who often earn far more money and receive much better benefits than the people that pay them (via their taxes) howling their outrage at the Republican Governor, Scott Walker, because the state workers lost the Collective Bargaining option based on an attempt by the (newly elected) Republicans to curb state spending (and subsequent taxation) is hardly an excuse to act like a mob of thugs. If the people of Wisconsin are foolish enough to actually recall the governor and/or Republican legislators they will get the government they deserve - good and hard.
In Wisconsis, where the union leadership is very radical, once the issue gained national prominence, the fringes started agitating for a recall and the regular left had to go all in. I suspect that most national leaders aren't happy..because it won't work...and that a lot of $$$ to toss away..
