Katrina vanden Heuvel’s proposal for proportional representation in multi-member districts overlooked the consensus among political scientists that our historic preference for single-member districts is what facilitated the creation of a two- party system [“Fair representation in the House,” op-ed, Aug. 20]. Where we see multi-member districts around the world, we also see a multiplicity of parties, with a resultant instability of governments.

Requiring the creation of fair, compact and contiguous districts is a far superior solution to the problems created by partisan gerrymandering.
