The National Republican Congressional Committee has canceled its TV reservations for Rep. Kevin Yoder (R-KS), making him the sixth House incumbent that either the group or its closely aligned super-PAC are leaving for dead heading into the campaign’s final month.

The NRCC canceled the ads in recent days, GOP sources confirm, walking away from Yoder in a suburban Kansas City district that President Trump lost by 1 point in 2016. Yoder is facing attorney and former mixed martial arts fighter Sharice Davids in the seat. If she wins, which now looks likely, she’ll become the first Native American woman and only the second openly gay woman ever to be elected to Congress.

He joins Reps. Mike Coffman (R-CO), Mike Bishop (R-MI), Barbara Comstock (R-VA), Rod Blum (R-IA) and Keith Rothfus (R-PA) as incumbents that either the NRCC or the Congressional Leadership Fund, the GOP’s main super-PAC, have been forced to give up on to save their money for more winnable districts.

These half-dozen members, paired with more than a half-dozen open that Republicans aren’t seriously spending in, give Democrats roughly half the seats they need for the House majority this fall.
