The Texas Republican Party tried to have its virtual state convention on Thursday, July 16, but could not handle the credentialing process. The party will try again on Saturday and Sunday, July 18-19. See this story. Thanks to Jim Riley for this news.
In fairness to the Republican Party, it had very little time to learn how to do an electronic convention. The city of Houston forced the city to abandon its in-person convention shortly before the scheduled date. The Texas Supreme Court sided with the city. The party could have held its in-person convention in another city but that would also have been a last-minute change.
