Pliego Carrasco criticizes the Alianza's filings by stating that they were based only on individual situations rather than a widespread study, that the information was based almost invariably on newspaper clippings, and that they only studied 26 districts. For his own study, Pliego Carrasco contrasted the growth in votes from the 2000 to the 2006 election for all parties. In all cases, the Alianza increased substantially more than the PAN, which even lost votes in the two categories of lowest marginalization. His conclusion is that there was no evidence that the PAN benefited from the expenditures. He found no statistical correlation between expenditures and the winning candidate. He derived similar conclusions for the other four programs. His conclusion is that the vote distribution does not support the hypothesis that social programs were used wholesale to influence the vote.
