RB Scott President John Mickelson gave a tour to Republican gubernatorial candidate Tim Michels, left, and Congressional candidate Derrick Van Orden on Friday.

EAU CLAIRE — With fewer than two months until the November election, the top candidates for the Third Congressional District seat are still trying to hammer out terms of a debate.

Derek Van Orden, a Republican, is challenging Democratic candidate State Sen. Brad Pfaff, D-Onalaska, for the open seat. Incumbent Ron Kind, D-La Crosse, is retiring, and nationally, Republicans view this seat as a likely pickup for their party.
