MADISON, Wis. (AP) — Republicans retained key congressional seats in Wisconsin with a third race still undecided early Wednesday morning. U.S. Rep. Bryan Steil won reelection to a fourth term representing southeast Wisconsin. He defeated Peter Barca, the last Democrat to hold the seat in 1995. Former gas station chain owner Tony Wied defeated Democrat Kristin Lyerly to win an open seat representing northeastern Wisconsin. The seat was vacant after Republican Mike Gallagher resigned earlier this year. In western Wisconsin, Republican U.S. Rep. Derrick Van Orden was trying to fend off Democratic challenger Rebecca Cooke. It was too early to call that race.
