In July this year, Laura Thompson was told by the Texas Secretary of State that she did not have the needed 500 valid signatures to be on the November 2016 ballot as an independent candidate for State Representative, 120th district. This announcement had been proved to be ironic on August 2, when Thompson was elected to the same district for a short term. She had been on the ballot in the special election easily, because Texas does not require any candidate in a special election to submit a petition.
Thompson did not agree that she had failed to get 500 valid signatures to be on the November 2016 ballot for the same office. She contested the ruling that her petition was not valid. Finally, on September 8, the Secretary of State changed his mind and said her petition is valid. See this story.
Obtaining 500 signatures may sound easy, but when the petitioning period is short, and when the law provides that no one who voted in the primary may sign (as Texas does), it is not easy.
Texas has a straight-ticket device, which will make it more difficult for Thompson to be re-elected. Thanks to Sidney Smith for the link.
