In "pure" rangeCardinal votingRatings", each voter may give any candidate any real number, but as the potential for [[tactical voting]] is huge, most systems use upper and lower bounds. For example, each voter might give a real number between -1 and 1, or an integer between 1 and 10.

RangeCardinal votingRatings in which only two different votes may be submitted (0 and 1, for example) is equivalent to [[approval voting]].

RangeCardinal votingRatings satisfies the [[monotonicity criterion]].

The scores for each candidate are summed, and the candidates with the highest sums are declared the winners.

In general, the optimal strategy for rangeCardinal votingRatings is to vote it identically to approval voting, so that all candidates are given either the maximum score or the minimum score. For more detailed strategies, see [[approval voting]].
