The latest round of congressional redistricting in the United States has been marked by aggressive partisan maneuvering, with President Trump reportedly urging Texas to deliver him five additional seats to help Republicans maintain control of the House in the upcoming midterms. This push comes despite historical precedent: since 1938, the party holding the White House has almost always lost House seats in midterm elections, with exceptions only when approval ratings topped 60 percent under Clinton in 1998 and Bush in 2002.
Trump's approval rating, currently mired in the mid-30s, suggests Republicans face stiff headwinds from inflation, high gas prices, and an unpopular war in Ukraine—a conflict many argue was enabled by Congress's failure to check executive power. In this environment, gerrymandered maps become a lifeline for incumbents.
While parliamentary systems like Canada's are also vulnerable to gerrymandering in theory, many have implemented safeguards. Canada, our northern neighbor, offers a compelling model. Since the Electoral Boundaries Readjustment Act of 1964, Canada has used small, independent commissions to draw electoral boundaries, effectively removing politicians from the process.
Canada's redistricting mechanics share similarities with the US: ridings are allocated to provinces based on decennial census data, and criteria include population equality, communities of interest, historical patterns, and geographic size. But the key difference is control. Each province's independent Federal Electoral Boundaries Commission holds public hearings where elected officials can speak but carry no extra weight. The final decision rests with the commission, not partisan legislators.
This contrasts sharply with the US, where state legislatures often control map-drawing, leading to self-serving districts that disenfranchise voters. As New York Democrats push redistricting amendments to flip seats, and California's primaries are reshaped by new maps, the partisan battle intensifies.
With advances in computational redistricting, algorithmic tools can carve districts with scalpel-like precision, enabling one party to dominate a state's delegation. The only way to break this cycle, experts argue, is to adopt non-partisan commissions nationwide or abolish the Electoral College—both requiring constitutional amendments unlikely in today's polarized climate.
Such reforms would give Republican voters in Massachusetts and Illinois fairer representation, and Democrats in Arkansas and Oklahoma a real voice. As Sheldon Jacobson, a computer science professor at the University of Illinois, notes, the problem isn't the algorithms—it's the partisanship they serve.
Canada discovered a solution 60 years ago. The roadblock to adopting it in the US is not practicality but politics. Until that changes, American voters will continue to be the losers in the remapping wars.
