Democrats are watching their own House seat lineup get lighted on the screen for redistricting rules reform. The results: The specter of Democrat Nate McMurray entering a February runoff that might be drawn up to frustrate him doesn’t bode well for the party’s electoral prospects in 2020.

New House of Representatives member Mark Walker has pushed Washington to formally consider retooling the drawing of the map with a new partisan boundary-drawing model as a first step in restoring faith in electoral systems and their fairness. At a committee hearing on Tuesday night, Walker said that the goal of the overhaul would be to ensure that congressional districts comply with election laws. The Congressional redistricting process has been subject to scandal since the 2008 Democratic takeover of the House led to the proliferation of “toss-up” districts in swing states and the redistricting of 31 districts in Ohio to reduce minority power in a competitive area.

On Tuesday, the Congressional Committee on Rules proposed an amendment to create a bipartisan redistricting commission to fine-tune the map. The ranking Democrat on the committee, Representative Jim McGovern, broke from his colleagues to join Walker in introducing the amendment. But the proposal went down to defeat in a 13–6 vote.
