There is now some discussion of using the recall to oust Wisconsin Assemblyman Bill Kramer (R), the former Majority Leader, who was charged with felony sexual assault for groping a woman at a 2011 fundraiser. Republicans are trying to push Kramer out, either by resignation or expulsion (though they seem to have given up on expulsion). If he is convicted, he automatically loses the position). They are also discussing recalls, though since they adjourned for the year, the practical impact is quite limited.
The story notes that petitioners would have to get signatures equal to 25% of votes cast in the district in the 2010 gubernatorial election. As I've mentioned before, this fact is unclear and could be up for challenge -- they may have to get 25% of the total from the 2012 recall.
