MINNEAPOLIS, Minn. -- Wisconsin was a central theme at the dueling conservative and progressive conferences for online activists here, with both sides gearing up for the summer's state Senate recall elections that are widely seen as a referendum on Gov. Scott Walker's (R-Wis.) fight with public unions. At the RightOnline conference, conservative activists were calling Wisconsin residents about the nine recall elections at a phone bank sponsored by Americans for Prosperity (AFP), the conservative group funding the conference.
