These polls use ballot data from real public elections. For multi-winner elections, the results
presented here may differ slightly from the real results due to minor variations in the counting
rules. We are interested in presenting more real public elections as data become available,
although sometimes they come in formats that require tedious editing or programming to put into usable form,
so there is generally always a backlog of data to be processed.
Cambridge has used ranked-choice voting since 1941

The first few San Francisco elections are highlighted here. More recent results for

They use an elegant rule for duplicate rankings,

duplicates, but they could be preprocessed to give the same result.
