At MPR Day at the Minnesota State Fair, MPR’s Mike Mulcahy hosts a gubernatorial debate at Dan Patch Park between U.S. Representative Tim Walz, the DFL candidate; and Hennepin County Commissioner Jeff Johnson, the GOP candidate. The two spar over Trump, schools, gun control measures, and how to slow the rising cost of health care.

The stakes are high for both parties. Republicans have complete control of the Legislature and could control all of state government if they win the governor's office this fall, but they haven't managed to win a statewide race in more than a decade.
