According to WisPolitics, Wisconsin Secretary of State Doug La Follette will put his name in the mix of Democrat candidates for Walker's recall election.
You may remember La Follette who stood as the last line of defense against the collective bargaining-rights stripping bill. He ordered the Legislative Reference Bureau to not publish the bill following a court order, because the Republicans violated the Open Meetings Law. Then, he later waited until the last minute to publish it when the decision was overturned. He stayed within the legal boundaries, doing exactly what the law required of him to do, but he helped as much as he could.
