Abstract: We apply the Thurstone method of unidimensional psychometric scaling to data sampled by CNI/IBOPE in three di¤erent periods before the Brazilian presidential election in 2010 regarding voting intention with respect to the main three candidates. Our results coincide with the overall rank of the candidates in each period and with the switch between the two main candidates in the last quarter before the election.
