On Friday, Republicans in the state assembly started voting on the budget repair bill before the session was scheduled to start. When Democrats arrived (again, before the session was scheduled to begin), Republicans were on the 3rd motion and the microphones for the Democrats had been turned off. When he was finally able to speak, Gordon Hintz, a representative from Oshkosh, was irate. This video of Hintz speaking is making the rounds on facebook, etc.; it sort of explains the tone that has been brewing in Wisconsin for a while.

FYI, the vote was later rescinded.
