This process continues until a candidate is declared elected. Because IRV allows voters to express their choices more fully than in plurality elections, the voting equipment has to allow for this greater precision. In a plurality election, voting equipment can simply store running totals for each candidate. In an IRV election, the voting equipment must create a data set that consists of a list of each voter s ranking. Consider a race with 4 candidates, and assume that voters can rank up to 3 choices.
Several vendors make equipment that is compatible with IRV elections.
London is seriously considering optical scanning equipment similar to that used in Cambridge, and Ireland appears to be leaning toward touch screen equipment. 6930 Carroll Ave.
