U.S. Senate candidates Norm Coleman and Al Franken gave similar views on key issues for rural voters on Tuesday, but offered different arguments for why they'd be better for the job. Coleman, the Republican incumbent, and Democrat Franken were joined at the annual FarmFest show by Independence Party candidates Dean Barkley and Steve Williams. All four talked up the importance of renewable fuel research and production on Minnesota's farms. Coleman and Franken, in their first joint appearance of the campaign, praised the recently passed farm bill, with both calling it a needed safety net for farmers. The forum's format didn't give candidates much chance to directly engage each other, putting the emphasis on discussion of issues.
