With Congress increasingly polarized, there are growing calls to replace the winner-take-all approach for House elections with a system that advocates say could better reflect the country's diversity.

There’s a spectrum of ways to reform the House using proportional representation. Two key factors are how many representatives a multi-member district would have and how winners of House seats would be proportionally allocated.

In 2021, Rep. Don Beyer of Virginia led a group of other House Democrats in reintroducing a proposal that’s been floating around Congress since 2017. The Fair Representation Act would require states to use ranked choice voting for House races. It calls for states with six or more representatives to create districts with three to five members each, and states with fewer than six representatives to elect all of them as at-large members of one statewide district.
