Minnesota's candidates for governor are keeping busy Friday as they prepare for another debate this weekend, the first in the Twin Cities.

Gov. Mark Dayton is speaking Friday morning at a leadership summit of the Minnesota State College Student Association in Bloomington.

Dayton also has an active official schedule Friday, with a handful of events closed to the press: a conference call with executives at BNSF Railway and Minnesota Power; a special Cabinet meeting for an update on Minnesota's Ebola preparedness and prevention efforts; and an evening banquet of the Minnesota State Fire Chiefs Association.

Republican Jeff Johnson does not have public events on his calendar Friday. His campaign said he would be fundraising and doing media interviews, and on Saturday had plans for retail campaigning in a number of locations.

Hannah Nicollet from the Independence Party has several campaign events Friday and Saturday as well. She's appearing Friday night on Duluth Almanac Extra, and at a Saturday conference in favor of marijuana legalization.

Dayton and Johnson are set to debate Sunday morning. It will be aired live on Fox 9 in the Twin Cities.
