MADISON, Wis. (AP) – Singers are holding dueling protests at the Wisconsin Capitol.  A loosely organized group of protesters known as the Solidarity Singers sang outside Monday after members were arrested three days in a row last week for failing to get a permit to be inside the building. The group has been holding noon sing-alongs at the Capitol nearly every day for two years.  The rotunda was occupied by a largely Republican group that supports the Gov. Scott Walker. Conservative blogger David Blaska says he organized that sing-along to show just how easy it is to get a free permit.  Capitol police began their crackdown on protesters without permits after a federal judge ruled earlier this month that large groups must have a permit to gather in the building.
