The tide appears to be turning against this particular form of fraud in South Texas’ Rio Grande Valley: Cutting a deal with an adult day care center owner can be one of the most productive vote harvesting operations an unscrupulous political candidate can undertake. This is how it works. The candidate cuts a deal with an adult day care provider and not only gets a campaign worker, or politiquera, to bus dozens of elderly voters to the polls, but also insists that the voters need “assistance” when casting their vote. The politiquera offering the assistance ensures that the voter votes the right way… The operation could have harvested 300-plus votes for a slate of three local candidates, a handy total to have on the first day of early voting. However, Hidalgo County District Attorney Rene Guerra stepped in and stopped it.
