At least one Reddit user claims he or she wasn't registered to vote after visiting a taco truck in Houston that was handing out voter registration forms.

But an organizer of the "Guac the Vote" campaign said that person most likely wasn't registered to vote because he or she did not mail in their form.

"We responded to that comment on Reddit. Our immediate goal is to make sure everyone is able to vote," said Carlos Duarte, Texas state director with Mi Familia Vota. "It's unfortunate and we're really interested in having this individual registering to vote, but they have not reached out to us."

User IPlayMyKazoo wrote on the Reddit post, "I ordered tacos and handed the paper to them, she looked at it then seemed to file it away, so I figured all was well. It's not a scam or anything, it was set up by a well-known voter advocacy group, and they were official registrars, I guess it just fell through the cracks."

Duarte said Mi Familia Vota gave voter registration forms to taco truck owners, who were then instructed to hand them out to people interested in registering. Duarte said it was up to the people to fill out the forms and mail them in.

"It's really difficult to say how many people actually registered," Duarte said of the "Guac the Vote" campaign. But Duarte does consider the campaign a success because it raised attention on how to become involved in the voting process.

Oct. 11 was the deadline to register to vote for the general election, which is Tuesday. Some taco trucks that participated in the campaign include Tacos Tierra Caliente on West Alabama and El Taquito Food Truck on Richmond.

As for the Reddit user who turned his or her voting form into the taco truck, an election worker said he or she could still vote, but it would be under review. "And at the review they would basically triple check to see if I was registered, and if not my vote wouldn't count," IPlayMyKazoo wrote.
