Are hungry kids a priority for the Harper government? by Larry Powell The forum (for the riding of Dauphin - Swan River - Neepawa) was sponsored by the Mission and Services Committee of the Neepawa United Church. It drew about 80 people to the church on Wednesday. But only four of the five candidates (see below) took part in the debate -  Ray  Piché  (Liberal),   Kate Storey (Green Party),  Inky Mark (Ind.) and  Laverne Lewycky (NDP) .

She said the night of the event, he was in Inglis, a small town in the western part of his riding.  This morning, however, Sopuck himself told PinP he had actually been in Roblin, a larger town just north of Inglis. A newspaper ad indicated it was a "meet and greet" affair. But that was in the morning in Roblin, a town within a 3-hour drive of Neepawa. So it's still not clear what the event in Inglis was which took priority over a candidate's forum. The MP bristled at my suggestion th
