Paul Mitchell, the data consultant who designed California’s Proposition 50 congressional map, is calling for a nationwide end to partisan gerrymandering. Mitchell’s work helped Democrats flip five Republican-held House seats in the November midterm elections, yet he argues in a recent op-ed that the practice of drawing districts for political advantage should be abolished.

Proposition 50, approved by California voters in November 2025, temporarily replaced the state’s independently drawn congressional districts with a map favored by Democrats for elections through 2030. Mitchell, the vice president of Political Data Inc. and owner of Redistricting Partners, stated that the measure was a necessary response to redistricting efforts in Texas and other states but should not become permanent.

What the Left Is Saying

Mitchell acknowledged in his San Francisco Chronicle op-ed that Proposition 50 was designed to benefit Democrats, describing it as a temporary countermeasure to Republican-led redistricting initiatives.

He argued that lawmakers should "kill partisan gerrymandering for good" and suggested that the incoming Congress make national redistricting a priority by establishing minimum standards for how all states draw their districts.

In an interview with Fox News Digital, Mitchell noted that he had planned to advocate for redistricting reform regardless of the election outcome. "I wasn’t trying to do this [op-ed] to time with anyone’s efforts to do further gerrymandering," Mitchell said. "I always planned on doing this as soon as the election was over."

He added that he had previously supported legislation by Representative Zoe Lofgren to set national redistricting standards and stated, "If then someone had said 'congress will be banning mid-decade redistricting' we would have been all for it."

The California Democratic Party framed Proposition 50 as a "direct response to a Republican power grab orchestrated by President Donald Trump and state leaders in Texas," who had redrawn their own congressional district lines to gain five additional House seats.

Democratic Governor Gavin Newsom also defended the measure in a November 4 social media post, stating that Prop 50 "is about standing up to bullies like Donald Trump."

What the Right Is Saying

Mitchell suggested that the recent political losses might make Republicans more open to redistricting reform, a stance they have previously opposed. "What makes now really important is that Republicans, who have opposed redistricting reform, should now realize that they lost in this war, so getting out of future wars is something maybe they would take more seriously now," Mitchell said.

He argued that while a ban on mid-decade redistricting is a necessary first step, it alone would not prevent partisan gerrymandering when states redraw maps after each census.

Mitchell identified independent commissions in every state as the "best solution" to end the practice. He emphasized that California’s current maps will remain in place through 2030, but the focus should shift to restoring a fairer process in 2031.

In a November 8 interview, Mitchell stated it would have been "a huge mistake" for Democrats to "sit" on their "laurels" regarding the need for structural reform.

What the Numbers Show

According to the Associated Press, Democrats succeeded in flipping all five House seats in California that were targeted by the party's redistricting push in the November midterm elections.

Proposition 50 was approved by voters in November 2025, altering the state's congressional boundaries for the 2026, 2028, and 2030 election cycles.

Mitchell’s firm, Redistricting Partners, has conducted more than 100 redistrictings for states, cities, school boards, and community college districts, including work for the State of New York Independent Redistricting Commission and the Los Angeles City Council Redistricting Commission.

Following the elections, Roll Call reported that some states have floated redrawing their congressional maps ahead of the 2028 cycle. Meanwhile, outgoing Republican Georgia Governor Brian Kemp announced on November 4 that he would not call a special legislative session to redraw maps or limit the powers of the incoming governor.

The Bottom Line

The debate over redistricting continues to shape the political landscape as states consider how to draw maps for the upcoming election cycles.

Mitchell’s call for a ban on mid-decade redistricting and the establishment of independent commissions highlights the tension between short-term political gains and long-term structural reform.

While California’s maps are set through 2030, the potential for further redistricting conflicts in other states remains a significant issue for the incoming Congress and state legislatures.
