Eric Pratt's commanding position in the MN-02 Republican primary reflects Tyler Kistner's mid-April withdrawal due to Marine Corps Reserve deployment, which cleared the primary field ahead of the August 11 vote. Pratt, a four-term state senator, secured the party's endorsement with 65 percent delegate support at the May 2 convention after a late challenger entered and then exited with an endorsement. Traders price this outcome at 90.5 percent for Pratt and 1.1 percent for Kistner, consistent with the absence of viable opposition. Potential shifts remain limited to any last-minute filings or unexpected endorsement reversals before the primary deadline.
