n mn For use Monday M.E. (i also filed newscast tape re: poll reax sunday) ALL five DFL Gubernatorial candidates campaigned either by BUS or by PHONE over the weekend....hoping to get the votes needed to win tomorrow's primary. Minnesota Public Radio's Karen-Louise Boothe was on the trail with SOME of them and has this report: After logging HUNDREDS of miles around the state since Thursday---DFL Endorsed candidate Mike Freeman maintained his fire during a rally at the American Legion Club in downtown Virginia. He said It was his 18-th trip to the iron range, since he began this race. It's a region of the state that's a DFL stronghold--and a KEY to winning an election.
