When one considers that there have been just 4 recall elections in Wisconsin history, this is pretty impressive, there are additionally 3 recall elections against Democratic state senators, but, as anyone who follows Maddow knows, the effort was significantly less grass roots and honest.  (Signatures for shots of booze)

Additionally, there was a special election in a solidly Republican district for the State Assembly, and it flipped to the Democrats for the first time in a rather long time.

The Dems have to win 3 seats to flip the Senate, which is a non-trivial task, but I think that the voters of Wisconsin are feeling a sh%$load of buyers remorse right now.
