I’m a little behind on the story, but when it’s all over I’m sure someone will put together a comprehensive article.  In a nutshell the governor is trying to bust all of the public sector unions.  The unions have taken to the streets (along with students).  The Governor announced “Cairo has come to Wisconsin” (did he really want to make that comparison?)  The bill was pushed in the state legislature where the Republicans hold a majority, but need at least one of the Democrats to have a quorum.  The Democrats left the building.  The governor sent the state police after them.  The Democrats left the state and are holed up somewhere in Illinois.

A more detailed summary.

And a clip of one of the demos.

If anyone has more information than that, please post it.
