Minnesota's D-F-L candidates for U.S. Senate faced some of the toughest questions of the campaign Monday when they met with activists and retired politicians in their own party at a Minneapolis drug store. A group known as "Tom's Salon" for Schneider Drug owner Tom SenGupta has been meeting at the drug store for the past twelves years to argue thorny policy issues. About 45 people crowded into the drug store's awkward spaces between greeting cards and figurines to put the candidates through their paces. Minnesota Public Radio's Amy Radil has this report.
