Seven instances in 15 years? Can anyone say “accidental”? In the many years I worked and taught in Texas elections, I never came in contact with anyone who would “on purpose” not have enough ballots in Spanish or English.
There have been many cases in the past of more people showing up at a polling place than there are paper ballots if those are being used. This is provided for by the Texas Election Code. A judge calls the election administrator or county clerk, whichever is running the election or in a primary where the county chairman is running the election, the judge calls him/her. Ballots are printed on a copy machine and each ballot given a different number. Those are taken to the polling place and the judge signs the back of each ballot making them legal ballots.
Also, in a strange case where new ballots couldn’t get there, a judge may use a blank piece of paper and make a hand written ballot, give it a number and sign it on the back and it’s a legal ballot.
Also, of course, if machines are used, they don’t run out of ballots.
People should learn how elections work in Texas before they shoot off their mouth.
Also, in Texas, a law requires a Spanish speaking person be available to interpret English for a Spanish speaking person if he/she needs help.
