Texas Election Code 174.021
“The delegates to a political party’s county conventions held under this chapter shall be selected in accordance with party rules AT precinct conventions held as provided by this subchapter.”
Any lawyer could tell you that “AT” is the key word here. Once this precinct conventions were over (adjourned) NO ONE has the authority to add delegates.
What I meant to say (it was pretty late when I wrote the post to which you were responding) was that the names were submitted to the caucus for approval. In the precinct caucus I attended, there were enough available delegate posistions to allow everyone attending the caucus to be a delegate, and every one of us signed up. There were also a few people who voted in the primary who couldn’t attend the caucus but were interested in being delegates. They gave their names to either election judges or party official who then forwarded them to the precinct caucuses where they were acted upon. My precinct had more than enough available spots for delegates, so everyone who wanted to be a delegate was approved. Apparently there were some precints where the people running the caucuses were not aware that attendance at the caucuses was not required to be a delegate and didn’t act on any of the names forwared by the election judges to the caucuses.
