Unsplit the Vote and Approval Voting sponsored the New Hampshire Liberty Forum 2019 put on annually by the Free State Project. Long-time Approval Voting activists Frank Atwood and Blake Huber flew out from Colorado.
There are three kinds of voting methods— allocative, comparative, and evaluative—based on the expression form and constraint. Allocative methods give each voter a fixed amount of “vote” (continuously divisible or as discrete tokens) to allocate among candidates. Comparative methods allow voters only to show preference between pairs of candidates; generally, this is done by ranking them. Evaluative methods have voters rate candidates independently on a scale (numeric or graded). There are also hybrids, e.g. multi-stage voting methods that combine voting methods of different categories.
