The first head-to-head debate between GOP Gov. Butch Otter and Democratic challenger Keith Allred will take place tomorrow in Idaho Falls, at the Idaho Falls City Club. New University of Idaho political scientist David Adler, who recently left ISU after 25 years, will moderate. The Idaho Falls Post Register reported today that the format for the debate will include both candidates submitting questions to Adler to ask the other, and lots of back-and-forth between the two that Adler said "should really bring an edge to it." It's the first of four scheduled face-offs between the two major-party candidates for governor. Boise TV station KTVB has announced it'll show the Idaho Falls debate live on its website, www.ktvb.com, starting shortly after noon, and AP reporter John Miller will be in Idaho Falls to cover the matchup; I'll post his reports here as soon as they're available. Adler told the Post Register he's expecting a sellout crowd of more than 300 people at the event.
