Lt. Gov Rebecca Kleefisch has criticized the potential Gubernatorial recall as a waste of money, potentially costing $7.7 million, that could be used elsewhere. Politifact checks her math, and finds out she's right, and might be low (could be $8-10 million). As a comparison, the costs of the Gray Davis recall was in the area of $66 million. The article criticizes her for claiming that the money will come from teacher raises or health care, but I think her point is valid -- it'll come from somewhere.
As I mentioned before, this could be a good line of arguments to lay down if not for the recall itself, than for the November election.
