Having already debated nearly two dozen times, the three major-party candidates will face off again Saturday.

DFLer Mark Dayton, Republican Tom Emmer and the Independence Party's Tom Horner will debate for an hour, starting at 6 p.m., with the showdown being aired live on KSMP-TV, channel 9. They will be questioned by three local political reporters and students from Hamline University in St. Paul, where the debate will be held.
