From the opinion:

Here, the provision of tacos did not reward any voter for voting, or voting for any particular person. The tacos were given to the entire community, including people who obviously could not vote, including children. All witnesses testified that Lopez never asked for a vote in exchange for a taco, and that he never asked if any of the recipients of the tacos had voted or were going to vote. Sanchez, the owner of the taco truck, testified he was told to give tacos to anyone who wanted one, and was not instructed to ask if people had voted in order to receive a taco.
