The race to represent Minnesota's 1st Congressional District will be among the most closely watched political contests in the nation this November. It's an open seat, after Democratic U.S. Rep. Tim Walz decided to run for governor. GOP candidate Jim Hagedorn is making his fourth bid for seat. He came within 3,000 votes of defeating Walz in 2016. Hagedorn, who grew up on a farm in Truman, later worked at the U.S. Department of Treasury. He faces DFL candidate Dan Feehan, an Army combat veteran from Red Wing who became a Defense Department official in the Obama administration. Hagedorn and Feehan joined Mike Mulcahy for a debate in MPR's UBS Forum.
