MADISON, Wis. (AP) — One of the hottest conversation topics in Wisconsin politics over the past week has been what people are finding in searches of thousands emails exchanged by Gov. Scott Walker's campaign staff and those who worked for him when he was Milwaukee County executive. Liberals and conservatives alike have been hunting the documents for their names as well as political friends and enemies. Some of the searches are for curiosity's sake. But operatives from across the political spectrum also are scouring the 28,000 pages of documents to find items they can use to attack or defend the state's most polarizing political figure. Democratic strategist Chris Lehane said it was "like winning the lottery" for people doing opposition research on Walker.
