But there’s a smaller category of lawmakers like Peterson and GOP Rep. Steve Chabot of Ohio who also merit attention: long-term incumbents of both parties fighting to preserve their careers.
Over 90% of House incumbents are usually reelected, thanks to name recognition and campaign fundraising advantages.
“There are people who traditionally voted Republican who don't identify with the current Republican Party," Schroder, 43, a businesswoman and local public health official, said in an interview.
Democratic and Republican campaign committees and other organizations allied with party leadership are aiming the bulk of their spending at each others' softest seats and defending vulnerable incumbents.
The Congressional Leadership Fund, aligned with House GOP leadership, planned to spend $3.3 million more, which Republicans said could grow.
