The use of choice voting in Cambridge, MA has enabled racial minorities to better succeed in local elections by lowering the threshold for election. Since 1980, when the African-American population crossed 10% of the town's total population, members of the African-American community have been consistently elected to the city council and school committee. Also as a result of ranked choice voting and its promotion of coalition-building, although only 10% of the population, in recent years African-Americans have been able to hold more than one seat on each board at time.
The implementation of ranked choice voting has allowed women to achieve much greater representation in Cambridge than in other methods of election. Between 1997 and 2001, the City Council and School Committee had female representation between 1/3 and 2/3 of each body.

In national elections, countries employing proportional voting methods have significantly higher voter turnout than countries with winner-take-all election systems. This has led political scientists like Seymour Martin Lipset and Walter Dean Burnham to the conclusion that proportional voting systems encourage greater voter participation. In this blog, George Pillsbury argues that turnout is higher in Cambridge because of voters' increased degree of choice and improved ability to elect candidates of choice.
