I believe they have passed it but the lefty Gov. Doyle vetoed it and there was not enough votes to override. It is my understand open carry is legal in Wisconsin and Doyle said that is O:K with him. Every law abiding gun owner in Wisconsin should start to daily open carry.
Open carry is ok in some rural areas of Wisconsin, but in practice, it will get you arrested for SOMETHING in most of the state.
Wisconsin, particularly Madison, is one of the most liberal areas of the entire country. Remember, besides Herb Kohl, the Diary Queen (you figure that name out), we have Russ Feingold, who thinks partial birth murder is fine.
