More Republican women than ever are seeking House seats this year after the 2018 election further diminished their limited ranks in Congress. The next test comes Tuesday in states such as Indiana, where Republican Rep. Susan Brooks one of 13 Republican women in the House is retiring. Republican women have always had a tougher time winning office. Groups that back GOP women have nowhere near the resources of organizations such as EMILYs List, which has existed much longer and has been a game changer for Democratic women. Hinson is running in the district represented by Democratic Rep. Abby Finkenauer, who is seeking a second term, and Miller-Meeks is seeking a seat vacated by Democratic Rep. Dave Loebsack.
